Sahih Muslim 623
وَحَدَّثَنَا مَنْصُورُ بْنُ أَبِي مُزَاحِمٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ أَبِي بَكْرِ بْنِ عُثْمَانَ بْنِ سَهْلِ بْنِ حُنَيْفٍ، قَالَ سَمِعْتُ أَبَا أُمَامَةَ بْنَ سَهْلٍ، يَقُولُ صَلَّيْنَا مَعَ عُمَرَ بْنِ عَبْدِ الْعَزِيزِ الظُّهْرَ ثُمَّ خَرَجْنَا حَتَّى دَخَلْنَا عَلَى أَنَسِ بْنِ مَالِكٍ فَوَجَدْنَاهُ يُصَلِّي الْعَصْرَ فَقُلْتُ يَا عَمِّ مَا هَذِهِ الصَّلاَةُ الَّتِي صَلَّيْتَ قَالَ الْعَصْرُ وَهَذِهِ صَلاَةُ رَسُولِ اللَّهِ صلى الله تعالى عليه وسلم الَّتِي كُنَّا نُصَلِّي مَعَهُ .
Mansur ibn Abi Muzahim narrated to us: Abdullah ibn al-Mubarak narrated to us, from Abu Bakr ibn Uthman ibn Sahl ibn Hunayf, who said: I heard Abu Umamah ibn Sahl say: We prayed the noon prayer with Umar ibn Abd al-Aziz, then went out and came to Anas ibn Malik, whom we found praying the afternoon prayer. I said, “Uncle, what prayer is this that you are praying?” He said, “The afternoon prayer. This is how the Messenger of Allah (peace and blessings be upon him) used to pray with us.”
