Sunan Ibn Majah 1211
It was
narrated that ‘Abdullah said:
“The Messenger of Allah (ﷺ)
offered prayer, and I am not sure whether he did something extra or
omitted something. He asked, and we told him, so he turned to face the
Qiblah and prostrated twice, then he said the Salam. Then he turned
to face us and said: ‘If any new command has been revealed
concerning the prayer, I would certainly have told you. But I am only
human and I forget and you forget. If I forget, then remind me. And
if anyone of you is uncertain about the prayer, let him do what is
closest to what is correct, then complete the prayer, say the Salam
and prostrate twice.”
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ مَنْصُورٍ، قَالَ شُعْبَةُ كَتَبَ إِلَىَّ وَقَرَأْتُهُ عَلَيْهِ قَالَ أَخْبَرَنِي إِبْرَاهِيمُ عَنْ عَلْقَمَةَ عَنْ عَبْدِ اللَّهِ قَالَ صَلَّى رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ صَلاَةً لاَ يَدْرِي أَزَادَ أَوْ نَقَصَ ‏.‏ فَسَأَلَ فَحَدَّثْنَاهُ فَثَنَى رِجْلَهُ وَاسْتَقْبَلَ الْقِبْلَةَ وَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ ‏
"‏ لَوْ حَدَثَ فِي الصَّلاَةِ شَىْءٌ لأَنْبَأْتُكُمُوهُ وَإِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ فَإِذَا نَسِيتُ فَذَكِّرُونِي وَأَيُّكُمْ مَا شَكَّ فِي الصَّلاَةِ فَلْيَتَحَرَّ أَقْرَبَ ذَلِكَ مِنَ الصَّوَابِ فَيُتِمَّ عَلَيْهِ وَيُسَلِّمَ وَيَسْجُدَ سَجْدَتَيْنِ ‏"‏ ‏.‏
