Companions of the Prophet
62/15. Chapter:
The merits of Sa'd bin Abi Waqqas Az-Zuhri رضي الله عنهما
وَبَنُو زُهْرَةَ أَخْوَالُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهْوَ سَعْدُ بْنُ مَالِكٍ.Banu Zuhra were maternal uncles of the Prophet ﷺ and he (i.e., Sa'd) was Sa'd bin Malik.
Sahih Bukhari
حَدَّثَنَا مَكِّيُّ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هَاشِمُ بْنُ هَاشِمٍ، عَنْ عَامِرِ بْنِ سَعْدٍ، عَنْ أَبِيهِ، قَالَ لَقَدْ رَأَيْتُنِي وَأَنَا ثُلُثُ الإِسْلاَمِ،.
Narrated Sa`d: No doubt, (for some time) I stood for one-third of the Muslims.
