Hadith 1528
Abud-Darda' (May Allah be pleased with him) said:
- وعن أبي الدرداء رضي الله عنه، عن النبي صلى الله عليه وسلم قال: "من رد عن عِرض أخيه، رد الله عن وجهه النار يوم القيامة" .((رواه الترمذي وقال حديث حسن.))
The Prophet (ﷺ) said, "He who defends the honour of his (Muslim) brother, Allah will secure his face against the Fire on the Day of Resurrection." [At-Tirmidhi].
In plain words
Whoever stands up to defend an absent brother's honour will have Allah shield his own face from the Fire on the Day of Resurrection. Defending the absent is rewarded by Allah's protection.
