‘O Messenger of Allah, has the prayer been shortened or did you forget?’ He said: ‘It has not been shortened and I did not forget.’ He said: ‘But you prayed two Rak’ah.’ He said: ‘Is what Dhul-Yadain says true?’ They said: ‘Yes.’ So he went forward and performed two Rak’ah and said the Salam, then he prostrated twice for prostrations of forgetfulness.
أَنَّ رَسُولَ اللَّهِ ﷺ سَهَا فَسَلَّمَ فِي الرَّكْعَتَيْنِ فَقَالَ لَهُ رَجُلٌ يُقَالُ لَهُ ذُو الْيَدَيْنِ يَا رَسُولَ اللَّهِ أَقَصُرَتِ الصَّلاَةُ أَمْ نَسِيتَ؟ قَالَ مَا قَصُرَتْ وَمَا نَسِيتُ قَالَ إِنَّكَ صَلَّيْتَ رَكْعَتَيْنِ قَالَ أَكَمَا يَقُولُ ذُو الْيَدَيْنِ؟ قَالُوا نَعَمْ فَتَقَدَّمَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ سَلَّمَ ثُمَّ سَجَدَ سَجْدَتَىِ السَّهْوِ
