The Messenger of Allah ﷺ led us five (rak'ahs in prayer). We said: Messenger of Allah, has the prayer been extended? He said: What is the matter? They said: You have said five (rak'ahs). He (the Holy Prophet) said: Verily I am a human being like you. I remember as you remember and I forget just as you forget. He then performed two prostrations as (compensation of) forgetfulness.
صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ خَمْسًا فَقُلْنَا يَا رَسُولَ اللَّهِ أَزِيدَ فِي الصَّلاَةِ قَالَ وَمَا ذَاكَ قَالُوا صَلَّيْتَ خَمْسًا قَالَ إِنَّمَا أَنَا بَشَرٌ مِثْلُكُمْ أَذْكُرُ كَمَا تَذْكُرُونَ وَأَنْسَى كَمَا تَنْسَوْنَ ثُمَّ سَجَدَ سَجْدَتَىِ السَّهْوِ
