Narrated 'Abdullah bin 'Umar:

The Prophet ﷺ passed by a man who was admonishing his brother regarding Haya and was saying, "You are very shy, and I am afraid that might harm you." On that, Allah's Apostle ﷺ said, "Leave him, for Haya is (a part) of Faith."

حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي سَلَمَةَ، حَدَّثَنَا ابْنُ شِهَابٍ، عَنْ سَالِمٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما مَرَّ النَّبِيُّ ﷺ عَلَى رَجُلٍ وَهْوَ يُعَاتَبُ فِي الْحَيَاءِ يَقُولُ إِنَّكَ لَتَسْتَحْيِي. حَتَّى كَأَنَّهُ يَقُولُ قَدْ أَضَرَّ بِكَ. فَقَالَ رَسُولُ اللَّهِ ﷺ
" دَعْهُ فَإِنَّ الْحَيَاءَ مِنَ الإِيمَانِ ".
