حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ قَالَ صَلَّيْتُ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِمِنًي رَكْعَتَيْنِ وَمَعَ أَبِي بَكْرٍ وَمَعَ عُمَرَ وَمَعَ عُثْمَانَ صَدْرًا مِنْ إِمَارَتِهِ ثُمَّ أَتَمَّ
مسند امام احمد بن حنبل · Hadith 4652
It was narrated that Ibn 'Umar said: I prayed two rak'ahs in Mina with the Prophet (PBUH) and with Abu Bakr, and with 'Umar, and with 'Uthmaan at the beginning of his caliphate, then he made it complete (i.e., four rak'ahs).
