أبو داود:١٢٩٩حَدَّثَنَا أَبُو تَوْبَةَ الرَّبِيعُ بْنُ نَافِعٍ حَدَّثَنَا مُحَمَّدُ بْنُ مُهَاجِرٍ عَنْ عُرْوَةَ بْنِ رُوَيْمٍ حَدَّثَنِي الأَنْصَارِيُّ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِجَعْفَرٍ بِهَذَا الْحَدِيثِ فَذَكَرَ نَحْوَهُمْ قَالَ فِي السَّجْدَةِ الثَّانِيَةِ مِنَ الرَّكْعَةِ الأُولَى كَمَا قَالَ فِي حَدِيثِ مَهْدِيِّ بْنِ مَيْمُونٍ
