أَخْبَرَنَا مُحَمَّدُ بْنُ هَاشِمٍ، أَنْبَأَنَا الْوَلِيدُ، أَنْبَأَنَا ابْنُ جُرَيْجٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُسَافِعٍ، عَنْ عُتْبَةَ بْنِ مُحَمَّدِ بْنِ الْحَارِثِ، عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ شَكَّ فِي صَلاَتِهِ فَلْيَسْجُدْ سَجْدَتَيْنِ بَعْدَ التَّسْلِيمِ ‏"‏ ‏.‏
