Arabic text
عن أبي هريرة رضي الله عنه أن النبي صلى الله عليه وسلم قال: «لا يُلْدَغُ المؤمنُ من جُحْرٍ واحد مرتين».
Translation
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: “The believer should not be stung twice from the same hole.”
Explanation
The noble Prophet (may Allah's peace and blessings be upon him) informs us that the believer should not be struck from the same place twice. So, a believer has to be sensible, cautious, and alert; otherwise, he will get easily deceived.
