The System of Ethics: Truthfulness First

The Meaning of Truthfulness (Ṣidq) in Language and Terminology

Linguistic meaning:
The word ṣidq (truthfulness) is the opposite of kadhib (falsehood). The root of ṣ-d-q indicates strength and firmness in something, whether in speech or in other matters. Truthfulness is called ṣidq because of its inherent strength, while falsehood has no strength—it is baseless and void. Some linguists said that its original meaning in Arabic denotes stability and firmness.
It is said: ṣaddaqahu — “he believed him,” meaning he accepted his statement; and ṣadaqahu al-ḥadīth — “he told him truthfully,” meaning he informed him with sincerity.
It is also said: ṣadaqtu al-qawma — “I spoke truthfully to the people”; and taṣādaqā — “they were truthful with one another,” whether in speech or affection.

Terminological meaning:
Truthfulness (ṣidq) is: “to report something in accordance with reality; it is the opposite of lying.”
Al-Bājī defined it as: “Truthfulness is describing something as it truly is.”
And al-Rāghib al-Aṣfahānī said: “Truthfulness is when one’s speech corresponds both to his inner belief and to the reality of what is spoken of; whenever one of these conditions is missing, the truthfulness is incomplete.”

Second: The Difference Between Truthfulness and Other Qualities

The Difference Between al-Ḥaqq (Truth/Reality) and al-Ṣidq (Truthfulness):
In language, al-ḥaqq means “that which is firm, established, and undeniable.” It comes from the verb ḥaqqa—“to be proven, to be obligatory.”
In the terminology of scholars of meanings (ahl al-maʿānī), al-ḥaqq refers to a judgment that conforms to reality. It is applied to statements, beliefs, religions, and doctrines insofar as they contain truth. Its opposite is al-bāṭil (falsehood).

As for al-ṣidq (truthfulness), it is most commonly used regarding speech specifically, and its opposite is al-kadhib (lying).
Thus, al-ḥaqq is broader in meaning, for it denotes “something being in its rightful place,” whereas al-ṣidq means “reporting something as it truly is.” Al-ḥaqq can apply both to speech and to nonverbal realities, while al-ṣidq applies only to statements.

Some scholars differentiate between them by noting that conformity is considered in al-ḥaqq from the side of reality itself, whereas in al-ṣidq, it is considered from the side of the statement or judgment.
Thus, the truthfulness (ṣidq) of a statement means its conformity with reality, while its rightness (ḥaqqiyyah) means that reality conforms to it.

The term al-ḥaqq may also be applied to the One who brings things into existence (i.e., God), to wisdom, or to that which exists in accordance with truth, as in the expressions: “Allah is the Truth” and “His word is the Truth.”

The Difference Between al-Wafā’ (Faithfulness) and al-Ṣidq (Truthfulness):
Some scholars said that the two are related as the general and the specific: every act of faithfulness (wafā’) is truthfulness (ṣidq), but not every act of truthfulness is faithfulness.
This is because faithfulness may occur through action without speech, whereas truthfulness exists only in words, since it is a type of statement (khabar).

Others, however, have said: truthfulness and faithfulness are twin qualities.

Encouragement Toward Truthfulness

A. From the Noble Qur’an

Islam commands truthfulness and strongly encourages it in all dealings and interactions of a Muslim.
There are numerous evidences from the Noble Qur’an supporting this noble character:

1. Allah Almighty says:

“O you who have believed, fear Allah and be with those who are true.”
— Surah At-Tawbah, 9:119

Meaning: Be truthful and adhere to truthfulness so that you will be among its people, saved from destruction, and granted relief and deliverance in your affairs.

2. Allah described Himself with truthfulness, saying:

“And who is more truthful than Allah in statement?”
— Surah An-Nisā’, 4:87

“And who is more truthful than Allah in speech?”
— Surah An-Nisā’, 4:122

That is, no one is more truthful than Allah in His words, reports, promises, and warnings. His speech is the highest form of truth—free from any falsehood whatsoever.

3. Allah the Exalted also says:

“And whoever obeys Allah and the Messenger—those will be with the ones upon whom Allah has bestowed favor: the prophets, the steadfast affirmers of truth, the martyrs, and the righteous. And excellent are those as companions.”
— Surah An-Nisā’, 4:69

Imam Ash-Shawkani explained:
“His saying ‘And whoever obeys Allah and the Messenger’ introduces a new statement highlighting the virtue of obedience. The phrase ‘those will be with the ones upon whom Allah has bestowed favor’ refers to entry into Paradise and reaching what Allah has prepared for them.
The term as-ṣiddīq (the steadfast in truth) refers to one who attains the highest degree of truthfulness. It may also mean the most virtuous followers of the prophets. The martyrs are those proven true in their testimony, and the righteous are those of righteous deeds.”

4. Allah says:

“Allah will say, ‘This is the Day when the truthful will benefit from their truthfulness. For them are gardens beneath which rivers flow, wherein they will abide forever. Allah being pleased with them and they with Him—that is the great attainment.’”
— Surah Al-Mā’idah, 5:119

Meaning: Their truthfulness in the worldly life benefits them in the Hereafter. Had they lied, Allah would have sealed their mouths and their limbs would testify against them, exposing them.
This verse encourages truthfulness and clarifies its great value and reward, for it will benefit a person in the most critical time—the Day of Judgment—when one is in utmost need of that which benefits him.

5. Allah the Exalted says:

“Indeed, the Muslim men and Muslim women, the believing men and believing women, the obedient men and obedient women, the truthful men and truthful women, the patient men and patient women, the humble men and humble women, the charitable men and charitable women, the fasting men and fasting women, the men who guard their chastity and the women who do so, and the men who remember Allah often and the women who do so—for them Allah has prepared forgiveness and a great reward.”
— Surah Al-Aḥzāb, 33:35

Meaning: Allah has prepared forgiveness and a mighty reward for those characterized by these noble traits—belief, devotion, truthfulness, patience, humility, charity, chastity, and remembrance of Allah—whether in faith, heart, speech, or action.
These virtues embody the essence of Islam, faith, and excellence (iḥsān).
For them, Allah promises forgiveness of their sins, as good deeds erase bad ones, and an immense reward beyond human comprehension—what no eye has seen, no ear has heard, and no heart has imagined.
We ask Allah to make us among them.

Such verses are among the strongest encouragements to embody truthfulness as one of the noblest of all virtues.

B - From the Prophetic Sunnah

The Prophetic traditions came abundantly urging truthfulness, commanding it, and showing that it is a path to Paradise.

1. Ibn Mas‘ūd (may Allah be pleased with him) narrated that the Messenger of Allah ﷺ said:

“Adhere to truthfulness, for truthfulness leads to righteousness, and righteousness leads to Paradise. A man keeps speaking the truth and strives to be truthful until he is recorded with Allah as a truthful one (ṣiddīq). And beware of lying, for lying leads to wickedness, and wickedness leads to the Fire. A man continues to lie and seeks falsehood until he is recorded with Allah as a liar.”
(Scholars said: This hadith urges striving for truthfulness, meaning being intentional and diligent about it, and warns against lying and being careless with it. When one becomes accustomed to lying, he becomes known for it, and Allah records him as a liar; and if he strives for truth, Allah records him among the truthful. “Recorded” here means judged as such and deserving of the corresponding reward or punishment.)

2. Al-Ḥasan ibn ʿAlī (may Allah be pleased with them both) said:

“I memorized from the Messenger of Allah ﷺ: ‘Leave that which makes you doubt for that which does not make you doubt, for truthfulness is tranquility, and falsehood is doubt.’”
Meaning: abandon what you are unsure about—whether it is good or evil, lawful or unlawful—and turn to what you are certain about. Truth brings peace to the heart, while lying brings anxiety and disturbance.
Al-Tūribishtī said: “The believer’s soul finds peace in truth and is disturbed by falsehood. So, if you feel doubt about something, avoid it; that doubt is a sign of falsehood. But when your heart feels assured, that is a sign of truth—so hold to it.”

3. In the narration of Abū Sufyān regarding the story of Heraclius, the ruler of Rome, he said:

“Heraclius asked me, ‘What does he (the Prophet ﷺ) command you to do?’ I said: ‘He commands us to worship Allah alone, associate nothing with Him, abandon what our forefathers said, and he orders us to pray, to be truthful, chaste, and to maintain kinship ties.’”

4. Al-Miswar ibn Makhramah (may Allah be pleased with him) reported:

“When the delegation of Hawāzin came as Muslims asking the Prophet ﷺ to return their property and captives, he said to them: ‘The most beloved speech to me is the truest one. So choose between one of the two groups—either the captives or the wealth.’”
His saying “The most beloved speech to me is the truest” indicates his desire for honesty from them and highlights that truthful words are dearest to him.

5. In the hadith of the first revelation:

“The Messenger of Allah ﷺ returned with the revelation trembling and said to Khadījah: ‘Cover me, cover me!’ They covered him until his fear subsided. Then he said, ‘O Khadījah, what is happening to me? I fear for myself!’ He told her what happened, and she said: ‘Never! Rejoice, for by Allah, Allah will never disgrace you. You maintain kinship, speak the truth, bear burdens, help the needy, honor the guest, and assist in all matters of truth.’”
The scholars said: Khadījah’s words mean that Allah would never harm someone endowed with such noble character and good deeds. Among these virtues is truthfulness, which is a protection from evil and disgrace.

C. Sayings of the Early Generations and the Scholars

• Abu Bakr al-Ṣiddīq (may Allah be pleased with him), when he was appointed Caliph, said:

“O people, I have been placed in authority over you, though I am not the best among you. If I do well, help me; if I do wrong, correct me. Truthfulness is a trust, and lying is betrayal.”

• ʿUmar ibn al-Khaṭṭāb (may Allah be pleased with him) said:

“For truth to lower me — and it rarely does — is more beloved to me than for lying to raise me — and it rarely does.”

• ʿUmar ibn al-Khaṭṭāb also said:

“Adhere to truthfulness, for if one of you thinks it will destroy him, it will actually save him.”

• Ismāʿīl ibn ʿUbayd Allāh said:

“ʿAbd al-Malik ibn Marwān used to order me to keep his sons from becoming fat, and he would command me not to feed them until they had gone out to the open air. He used to say: ‘Teach my sons truthfulness just as you teach them the Qur’an, and keep them away from lying, even if that means punishment — even death.’”

• Wahb said:

“Whoever is known for truthfulness is trusted with narrations.”

• Al-Fuḍayl ibn ʿIyāḍ said:

“There is no piece of flesh more beloved to Allah than a truthful tongue, and none more hated by Him than a lying tongue.”

• Al-Fuḍayl also said:

“People have never adorned themselves with anything better than truthfulness. Allah Almighty will question the truthful about their truthfulness — so what of the liars?” Then he wept.

• Al-Aḥnaf said to his son:

“My son, it suffices you, as an honor of truthfulness, that a truthful man’s word is accepted even against his enemy. And as for the baseness of lying — the liar’s word is not accepted, neither in favor of his friend nor his foe. Everything has an ornament, and the ornament of speech is truthfulness — it shows the balance of reason.”

• Ibrāhīm al-Khawwāṣ said:

“You will not see a truthful person except engaged in a duty he must perform, or in a good deed he is doing.”

• Maʿrūf al-Karkhī said:

“How many are the righteous! Yet how few are the truthful!”

• Imām al-Shāfiʿī said:

“The ultimate goal of every matter is truthfulness.”

• Abū Ḥātim ibn Ḥibbān said:

“Truthfulness raises a person in both worlds, just as lying brings him low in both. If truth had no other virtue except that once a man is known for it, even his mistakes are accepted as truth by those who hear him — that alone would make it obligatory on every rational person to train his tongue toward truth and avoid lying. Indeed, silence at times is better than speech, for any speech misplaced — silence is better than it.”

• Abū Ḥātim also said:

“Allah Almighty has honored the tongue above all other limbs, elevated its rank, and made its virtue clear by granting it the power of speech to declare His Oneness. Therefore, it is not fitting for a rational person to accustom this instrument, created to proclaim monotheism, to lying. Rather, he must constantly guard it with truthfulness, for the tongue produces what it is trained for — if truth, then truth; if falsehood, then falsehood.”

• Al-Junayd said:

“The essence of truthfulness is to tell the truth in a situation where nothing can save you except lying!”

• Al-Qīnī said:

“I strive to be truthful in small matters that may harm me so I can be truthful in great matters that benefit me.”

• Ismāʿīl ibn ʿUbayd ibn Abī al-Muhājir said:

“When my father was near death, he gathered his sons and said:
‘O my sons, fear Allah, remain devoted to the Qur’an, and hold firmly to truthfulness — even if one of you were to kill someone and was asked about it, let him confess. By Allah, I have never told a lie since I first read the Qur’an. O my sons, keep your hearts pure toward all Muslims. By Allah, I have reached a state where I leave my house and meet any Muslim, and what I hold in my heart for him is the same as what I hold for myself. Do you not see that I wish for myself nothing but good?’”
