Sunan an-Nasa'i 1685
It was narrated from Ibrahim bin Muhammad Al-Muntashir, from his father, that:
He was in the masjid of 'Amr bin Shurahbil and the iqamah for prayer was said, and they were waiting. He came and said: "I was praying witr." Abdullah was asked: "Is there any witr after the adhan?" He said: "Yes, and after the Iqamah." And he narrated that the Prophet (ﷺ) once slept and missed the prayer until the sun had risen, then he prayed.
أَخْبَرَنَا يَحْيَى بْنُ حَكِيمٍ، قَالَ حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنْ إِبْرَاهِيمَ بْنِ مُحَمَّدِ بْنِ الْمُنْتَشِرِ، عَنْ أَبِيهِ، أَنَّهُ كَانَ فِي مَسْجِدِ عَمْرِو بْنِ شُرَحْبِيلَ فَأُقِيمَتِ الصَّلاَةُ فَجَعَلُوا يَنْتَظِرُونَهُ فَجَاءَ فَقَالَ إِنِّي كُنْتُ أُوتِرُ ‏.‏ قَالَ وَسُئِلَ عَبْدُ اللَّهِ هَلْ بَعْدَ الأَذَانِ وَتْرٌ قَالَ نَعَمْ وَبَعْدَ الإِقَامَةِ ‏.‏ وَحَدَّثَ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ نَامَ عَنِ الصَّلاَةِ حَتَّى طَلَعَتِ الشَّمْسُ ثُمَّ صَلَّى ‏.‏
