وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ مَرَّ عَلَى رَجُلٍ مِنَ الأَنْصَارِ وَهُوَ يَعِظُ أَخَاهُ فِي الْحَيَاءِ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ: دَعْهُ فَإِنَّ الْحَيَاءَ مِنَ الإِيمَانِ ((مُتَّفَقٌ عَلَيْهِ)) .
Ibn 'Umar (May Allah be pleased with them) reported: Messenger of Allah (ﷺ) passed by a man of the Ansar who was admonishing his brother regarding shyness. Messenger of Allah (ﷺ) said, "Leave him alone, for modesty is a part of Iman." [Al-Bukhari and Muslim].
