Narrated by:Anas bin Malik that he said
It was narrated from Anas bin Malik that he said:"I prayed two rak'ahs with the Messenger of Allah (ﷺ) in Mina, and with Abu Bakr and 'Umar, and two rak'ahs with 'Uthman at the beginning of his Caliphate."
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ بُكَيْرٍ، عَنْ مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي سُلَيْمٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّهُ قَالَ صَلَّيْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم بِمِنًى وَمَعَ أَبِي بَكْرٍ وَعُمَرَ رَكْعَتَيْنِ وَمَعَ عُثْمَانَ رَكْعَتَيْنِ صَدْرًا مِنْ إِمَارَتِهِ .
