Muwatta Imam Malik Book of Good Character, Hadith 9

Yahya related to me from Malik from Salama ibn Safwan ibn Salama az-Zuraqi that Zayd ibn Talha ibn Rukana, who attributed it to the Prophet ﷺ said, "The Messenger of Allah ﷺ said, 'Every deen has an innate character. The character of Islam is modesty.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سَلَمَةَ بْنِ صَفْوَانَ بْنِ سَلَمَةَ الزُّرَقِيِّ، عَنْ زَيْدِ بْنِ طَلْحَةَ بْنِ رُكَانَةَ، يَرْفَعُهُ إِلَى النَّبِيِّ ﷺ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " لِكُلِّ دِينٍ خُلُقٌ وَخُلُقُ الإِسْلاَمِ الْحَيَاءُ " .
