البيهقي:٣٧٩٧ – أَخْبَرَنَا أَبُو الْحُسَيْنِ عَلِيُّ بْنُ مُحَمَّدِ بْنِ عَبْدِ اللهِ بْنِ بِشْرَانَ الْعَدْلُ بِبَغْدَادَ أنبأ إِسْمَاعِيلُ بْنُ مُحَمَّدٍ الصَّفَّارُ وَأَبُو جَعْفَرٍ مُحَمَّدُ بْنُ عَمْرٍو الرَّزَّازُ قَالَا ثنا سَعْدَانُ بْنُ نَصْرٍ ثنا مُحَمَّدُ بْنُ عُبَيْدٍ عَنْ مِسْعَرٍ عَنْ مَنْصُورٍ عَنْ إِبْرَاهِيمَ عَنْ عَلْقَمَةَ عَنِ ابْنِ مَسْعُودٍ قَالَ

قَالَ رَسُولُ اللهِ ﷺ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَأَيُّكُمْ شَكَّ فِي صَلَاتِهِ فَلْيَنْظُرْ أَحْرَى ذَلِكَ إِلَى الصَّوَابِ فَلْيُتِمَّ عَلَيْهِ وَيَسْجُدْ سَجْدَتَيْنِ  

أَخْرَجَهُ مُسْلِمٌ مِنْ حَدِيثِ مِسْعَرِ بْنِ كِدَامٍ وَأَخْرَجَهُ الْبُخَارِيُّ مِنْ وَجْهٍ آخَرَ عَنْ مَنْصُورِ بْنِ الْمُعْتَمِرِ
