Arabic text
عَن أَبِي أُمَامَةَ قَالَ: حَدَّثَنِي عَمْرُو بْنُ عَبَسَةَ رضي الله عنه أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «أَقْرَبُ مَا يَكُونُ الرَّبُّ مِنَ العَبْدِ فِي جَوْفِ اللَّيْلِ الآخِرِ، فَإِنْ اسْتَطَعْتَ أَنْ تَكُونَ مِمَّنْ يَذْكُرُ اللَّهَ فِي تِلْكَ السَّاعَةِ فَكُنْ».
Translation
Abu ’Umāmah reported: ‘Amr ibn ‘Abasah (may Allah be pleased with him) related to me that he heard the Prophet (may Allah's peace and blessings be upon him) say: "The nearest the Lord to a servant is in the course of the last part of the night. So, if you are able to be among those who remember Allah at that hour, do so."
Explanation
The Prophet (may Allah's peace and blessings be upon him) informs that the Almighty Lord becomes closest to the servant in the last third of the night. So, if you, O believer, find the success and ability to be among those who worship, pray, remember, and repent at this time, indeed it is something that should be seized and diligently achieved.
