Narrated Ibn Shihab: Once `Umar bin `Abdul `Aziz delayed the `Asr prayer a little. `Urwa said to him, "Gabriel descended and led the prayer in front of the Prophet (ﷺ) " On that `Umar said, "O `Urwa! Be sure of what you say." "Urwa, "I heard Bashir bin Abi Masud narrating from Ibn Masud who heard Allah's Messenger (ﷺ) saying, 'Gabriel descended and led me in prayer; and then prayed with him again, and then prayed with him again, and then prayed with him again, and then prayed with him again, counting with his fingers five prayers."

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ شِهَابٍ، أَنَّ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، أَخَّرَ الْعَصْرَ شَيْئًا فَقَالَ لَهُ عُرْوَةُ أَمَا إِنَّ جِبْرِيلَ قَدْ نَزَلَ فَصَلَّى أَمَامَ رَسُولِ اللَّهِ صلى الله عليه وسلم. فَقَالَ عُمَرُ اعْلَمْ مَا تَقُولُ يَا عُرْوَةُ. قَالَ 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.
