Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ عَبْدِ اللَّهِ النَّيْسَابُورِيُّ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الأَنْصَارِيُّ، قَالَ أَخْبَرَنِي أَشْعَثُ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَبِي الْمُهَلَّبِ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم صَلَّى بِهِمْ فَسَهَا فَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ .
It was narrated from Imran bin Husain that: The Prophet (ﷺ) led them in prayer and forgot (how many rak'ahs he had prayed), then he prostrated twice, then he said the salam.
