(266) Chapter: Prohibition of Reviling a Muslim without any cause

Abu Hurairah (May Allah be pleased with him) said:
A drunkard was brought to the Prophet (ﷺ). He said, "Give him a beating." Then some beat him with their hands, some with their shoes, and some with (a folded) piece of cloth. When he left, someone said to him: "May Allah disgrace you!" The Prophet (ﷺ) said, "Do not help Satan overcome him by uttering such words."

[Al- Bukhari].

Commentary: We learn from this Hadith that imprecation against a sinner helps Satan because he is avowed to disgrace and humiliate Muslims before Allah. When a Muslim curses another Muslim and imprecates for hishumiliation and disgrace, he in fact tries to accomplish the mission of Satan because in doing so Satan will have achieved his objective. Therefore, one should not curse a fellow Muslim even if he or she is a sinner. In fact, one should pray to Allah for his or her guidance.
