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 " .
