[Machine] A man insulted another man in the presence of the Messenger of Allah ﷺ and the man retaliated. So the Messenger of Allah ﷺ said, "Whoever defends the honor of his brother, a barrier will be created between him and the Fire." This hadith was also narrated by Marzuq from Umm Ad-Darda from Abu Ad-Darda.
نَالَ رَجُلٌ مِنْ رَجُلٍ عِنْدَ رَسُولِ اللهِ ﷺ فَرَدَّ عَلَيْهِ رَجُلٌ فَقَالَ رَسُولُ اللهِ ﷺ مَنْ رَدَّ عَنْ عِرْضِ أَخِيهِ كَانَ لَهُ حِجَابًا مِنَ النَّارِ وَرَوَاهُ أَيْضًا مَرْزُوقٌ عَنْ أُمِّ الدَّرْدَاءِ عَنْ أَبِي الدَّرْدَاءِ مَرْفُوعًا
