(Imam Bukhari said that) Abdullah bin Muhammad narrated to us, he said that Abu Amir Al-Aqadi narrated to us, he said that Sulaiman bin Bilal narrated to us, from Abdullah bin Dinar, from Abu Salih, from Hazrat Abu Hurairah (may Allāh be pleased with him), he says that the Prophet ﷺ said:
Faith has more than sixty branches, and modesty is also a branch of faith.
حَدَّثَنَا عَبْدُ اللهِ بْنُ مُحَمَّدٍ ، قَالَ: حَدَّثَنَا أَبُو عَامِرٍ الْعَقَدِيُّ ، قَالَ: حَدَّثَنَا سُلَيْمَانُ بْنُ بِلَالٍ، عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ ﵁، عَنِ النَّبِيِّ ﷺ قَالَ
الْإِيمَانُ بِضْعٌ وَسِتُّونَ شُعْبَةً، وَالْحَيَاءُ شُعْبَةٌ مِنَ الْإِيمَانِ.
