‘Abd Allah (b. Mas’ud) said; The Messenger of Allah (ﷺ) led us in five rak’ahs of prayer. When he turned away (1:e, finished his prayer), the people whispered among themselves. He asked; what is the matter with you ? They said :

Messenger of Allah, has (the number of the rak’ahs of) the prayer been increased ? he said : No. they said; you have offered five rak’ahs of prayer. He then turned away and performed two prostrations, and afterwards gave the salutation. He then said : I am only a human being, I forget, as you forget.

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، أَخْبَرَنَا جَرِيرٌ، ح وَحَدَّثَنَا يُوسُفُ بْنُ مُوسَى، حَدَّثَنَا جَرِيرٌ، - وَهَذَا حَدِيثُ يُوسُفَ - عَنِ الْحَسَنِ بْنِ عُبَيْدِ اللَّهِ، عَنْ إِبْرَاهِيمَ بْنِ سُوَيْدٍ، عَنْ عَلْقَمَةَ، قَالَ قَالَ عَبْدُ اللَّهِ صَلَّى بِنَا رَسُولُ اللَّهِ صلى الله عليه وسلم خَمْسًا فَلَمَّا انْفَتَلَ تَوَشْوَشَ الْقَوْمُ بَيْنَهُمْ فَقَالَ ‏"‏ مَا شَأْنُكُمْ ‏"‏ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ هَلْ زِيدَ فِي الصَّلاَةِ قَالَ ‏"‏ لاَ ‏"‏ ‏.‏ قَالُوا فَإِنَّكَ صَلَّيْتَ خَمْسًا ‏.‏ فَانْفَتَلَ فَسَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ قَالَ ‏"‏ إِنَّمَا أَنَا بَشَرٌ أَنْسَى كَمَا تَنْسَوْنَ ‏"‏ ‏.‏
