أَخْبَرَنَا الْحَسَنُ بْنُ إِسْمَعِيلَ بْنِ سُلَيْمَانَ الْمُجَالِدِيُّ قَالَ حَدَّثَنَا الْفُضَيْلُ يَعْنِي ابْنَ عِيَاضٍ عَنْ مَنْصُورٍ عَنْ إِبْرَاهِيمَ عَنْ عَلْقَمَةَ عَنْ عَبْدِ اللَّهِ قَالَ صَلَّی رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَاةً فَزَادَ فِيهَا أَوْ نَقَصَ فَلَمَّا سَلَّمَ قُلْنَا يَا نَبِيَّ اللَّهِ هَلْ حَدَثَ فِي الصَّلَاةِ شَيْئٌ قَالَ وَمَا ذَاکَ فَذَکَرْنَا لَهُ الَّذِي فَعَلَ فَثَنَی رِجْلَهُ فَاسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ سَجْدَتَيْ السَّهْوِ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ لَوْ حَدَثَ فِي الصَّلَاةِ شَيْئٌ لَأَنْبَأْتُکُمْ بِهِ ثُمَّ قَالَ إِنَّمَا أَنَا بَشَرٌ أَنْسَی کَمَا تَنْسَوْنَ فَأَيُّکُمْ شَکَّ فِي صَلَاتِهِ شَيْئًا فَلْيَتَحَرَّ الَّذِي يَرَی أَنَّهُ صَوَابٌ ثُمَّ يُسَلِّمْ ثُمَّ يَسْجُدْ سَجْدَتَيْ السَّهْوِ
سنن نسائی · Hadith 1248
It was narrated that ‘Abdullah said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم prayed and did more or less (Rak’ahs). When he had said the Salam we said: ‘Messenger of Allah صلی اللہ علیہ وآلہ وسلم has there been some change concerning the prayer?’ He said: ‘Why are you asking?’ So we told him what he had done. He turned back toward the Qiblah and prostrated two prostrations of forgetfulness, then he turned to face us and said: ‘If there had been some change concerning the prayer I would have told you.’ Then he said: ‘Rather I am a human being and I forget as you forget. If any one of you is not sure about his prayer, let him estimate what he thinks is correct, and complete his prayer on that basis, then say the Taslimand prostrate two prostrations of forgetfulness.” (Sahih)
