حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ ، سَمِعَ عَبْدَ الْعَزِيزِ بْنَ عَبْدِ الصَّمَدِ ، حَدَّثَنَا مَنْصُورٌ ، عَنْ إِبْرَاهِيمَ ، عَنْ عَلْقَمَةَ ، عَنْ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ : أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، صَلَّى بِهِمْ صَلَاةَ الظُّهْرِ ، فَزَادَ أَوْ نَقَصَ مِنْهَا ، قَالَ مَنْصُورٌ : لَا أَدْرِي إِبْرَاهِيمُ ، وَهِمَ أَمْ ، عَلْقَمَةُ ، قَالَ : قِيلَ يَا رَسُولَ اللَّهِ : أَقَصُرَتِ الصَّلَاةُ أَمْ نَسِيتَ ؟ قَالَ : " وَمَا ذَاكَ " ، قَالُوا : صَلَّيْتَ كَذَا وَكَذَا ، قَالَ : " فَسَجَدَ بِهِمْ سَجْدَتَيْنِ ، ثُمَّ قَالَ : " هَاتَانِ السَّجْدَتَانِ لِمَنْ لَا يَدْرِي زَادَ فِي صَلَاتِهِ أَمْ نَقَصَ ، فَيَتَحَرَّى الصَّوَابَ : فَيُتِمُّ مَا بَقِيَ ، ثُمَّ يَسْجُدُ سَجْدَتَيْنِ " .
Narrated Ibn Mas`ud: that Allah's Prophet led them in the Zuhr prayer and he offered either more or less rak`at, and it was said to him, "O Allah's Apostle ! Has the prayer been reduced, or have you forgotten?" He asked, "What is that?" They said, "You have prayed so many rak`at." So he performed with them two more prostrations and said, "These two prostrations are to be performed by the person who does not know whether he has prayed more or less (rak`at) in which case he should seek to follow what is right. And then complete the rest (of the prayer) and perform two extra prostrations."
