Sunan an-Nasai Book 6, Hadith 494

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، أَخَّرَ الْعَصْرَ شَيْئًا فَقَالَ لَهُ عُرْوَةُ أَمَا إِنَّ جِبْرِيلَ عَلَيْهِ السَّلاَمُ قَدْ نَزَلَ فَصَلَّى أَمَامَ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَقَالَ 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 ‏.‏

It was narrated from Ibn Shihab that 'Umar bin 'Abdul-'Aziz delayed the 'Asr prayer a little. 'Urwah said to him:"Jibril came down and led the Messenger of Allah (ﷺ) in prayer." 'Umar said: "Watch what you are saying, O 'Urwah!" He said: "I heard Bashir bin Abi Mas'ud say: 'I heard Abu Mas'ud say: "I heard the Messenger of Allah (ﷺ) say: 'Jibril came down and led me in prayer, and I prayed with him, then I prayed with him, then I prayed with him, then I prayed with him, then I prayed with him - and he counted off five prayers on his fingers
