Clarifying the number of branches of faith, the best and the least of them, the virtue of modesty (Al-Haya') and the fact that it is part of faith
حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ وَقَالَ مَرَّ بِرَجُلٍ مِنَ الأَنْصَارِ يَعِظُ أَخَاهُ .
Zuhri has narrated this hadith with the addition of these words: He (the Prophet) happened to pass by a mass of Ansar who was instructing his brother (about modesty).
