The Messenger of Allah ﷺ led us in prayer and gave the salutation after two rakahs of prayer. He narrated this tradition like that of Ibn Sirin from Abu Hurairah. This version adds; he gave the salutation and prostrated two prostrations due to forgetfulness.  

أبو داود:١٠١٧حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ ثَابِتٍ حَدَّثَنَا أَبُو أُسَامَةَ ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ أَخْبَرَنَا أَبُو أُسَامَةَ أَخْبَرَنِي عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ

صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ فَسَلَّمَ فِي الرَّكْعَتَيْنِ فَذَكَرَ نَحْوَ حَدِيثِ ابْنِ سِيرِينَ عَنْ أَبِي هُرَيْرَةَ قَالَ ثُمَّ سَجَدَ سَجْدَتَىِ السَّهْوِ
