Muwatta Imam Malik Book of Good Character, Hadith 10

Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah from Abdullah ibn Umar that the Messenger of Allah ﷺ passed by a man who was chiding his brother about modesty. The Messenger of Allah ﷺ said, "Leave him. Modesty is part of iman."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ عَلَى رَجُلٍ وَهُوَ يَعِظُ أَخَاهُ فِي الْحَيَاءِ فَقَالَ رَسُولُ اللَّهِ ﷺ " دَعْهُ فَإِنَّ الْحَيَاءَ مِنَ الإِيمَانِ " .
