Narrated Abu Huraira:
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، حَدَّثَنَا يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ ، عَنْ عَمْرٍو ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " بُعِثْتُ مِنْ خَيْرِ قُرُونِ بَنِي آدَمَ قَرْنًا فَقَرْنًا، حَتَّى كُنْتُ مِنَ الْقَرْنِ الَّذِي كُنْتُ فِيهِ " .
Allah's Messenger (ﷺ) said, "I have been sent (as an Apostle) in the best of all the generations of Adam's offspring since their Creation."
