It was narrated from Ibn ‘Abbas that the Messenger of Allah said: “Every religion has its distinct characteristic, and the distinct characteristic of Islam is modesty.’”
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ، حَدَّثَنَا سَعِيدُ بْنُ مُحَمَّدٍ الْوَرَّاقُ، حَدَّثَنَا صَالِحُ بْنُ حَسَّانَ، عَنْ مُحَمَّدِ بْنِ كَعْبٍ الْقُرَظِيِّ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِنَّ لِكُلِّ دِينٍ خُلُقًا وَإِنَّ خُلُقَ الإِسْلاَمِ الْحَيَاءُ " .
