It was narrated that Ibrahim said:

"Alqamah prayed five (rak'ahs) and when he said the taslim, Ibrahim bin Suwaid said : 'O Abu Shibl, you prayed five!' He said: 'Is that true, O odd-eyed one?' Then he prostrated two prostrations of forgetfulness, then he said: 'This is what the Messenger of Allah ﷺ did.'"

أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ سُفْيَانَ، عَنِ الْحَسَنِ بْنِ عُبَيْدِ اللَّهِ، عَنْ إِبْرَاهِيمَ، أَنَّ عَلْقَمَةَ، صَلَّى خَمْسًا فَلَمَّا سَلَّمَ قَالَ إِبْرَاهِيمُ بْنُ سُوَيْدٍ يَا أَبَا شِبْلٍ صَلَّيْتَ خَمْسًا . فَقَالَ أَكَذَلِكَ يَا أَعْوَرُ فَسَجَدَ سَجْدَتَىِ السَّهْوِ ثُمَّ قَالَ هَكَذَا فَعَلَ رَسُولُ اللَّهِ ﷺ .
