Sahih Muslim 610 a
Ibn Shibab reported:
'Umar b. 'Abd al-'Aziz deferred the afternoon prayer somewhat and 'Urwa said to him: Gabriel came down and he led the Messenger of Allah (ﷺ) in prayer. 'Umar said to him: O 'Urwa, are you aware of what you are saying? Upon this he ('Urwa) said: I heard Bashir b. Abu Mas'ud say that he heard Abu Mas'ud say that he heard the Messenger of Allah (ﷺ) say: Gabriel came down and acted as my Imam, then I prayed with him, then I prayed with him, then I prayed with him. then I prayed with him. then I prayed with him. reckoning with his fingers five times of prayer.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح قَالَ وَحَدَّثَنَا ابْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، أَنَّ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، أَخَّرَ الْعَصْرَ شَيْئًا فَقَالَ لَهُ عُرْوَةُ أَمَا إِنَّ جِبْرِيلَ قَدْ نَزَلَ فَصَلَّى إِمَامَ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَقَالَ لَهُ عُمَرُ اعْلَمْ مَا تَقُولُ يَا عُرْوَةُ ‏.‏ فَقَالَ سَمِعْتُ بَشِيرَ بْنَ أَبِي مَسْعُودٍ يَقُولُ سَمِعْتُ أَبَا مَسْعُودٍ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏
"‏ نَزَلَ جِبْرِيلُ فَأَمَّنِي فَصَلَّيْتُ مَعَهُ ثُمَّ صَلَّيْتُ مَعَهُ ثُمَّ صَلَّيْتُ مَعَهُ ثُمَّ صَلَّيْتُ مَعَهُ ثُمَّ صَلَّيْتُ مَعَهُ ‏"‏ ‏.‏ يَحْسُبُ بِأَصَابِعِهِ خَمْسَ صَلَوَاتٍ ‏.‏
