حَدَّثَنَا ابْنُ صَاعِدٍ ، ثنا أَبُو عُبَيْدِ اللَّهِ الْمَخْزُومِيُّ سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ ، ثنا سُفْيَانُ ، عَنْ مَنْصُورٍ ، عَنْ إِبْرَاهِيمَ ، عَنْ عَلْقَمَةَ ، عَنِ ابْنِ مَسْعُودٍ ، " أَنَّهُ سَجَدَ سَجْدَتَيِ السَّهْوِ بَعْدَ التَّسْلِيمِ ، وَحَدَّثَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سَجَدَهُمَا بَعْدَ التَّسْلِيمِ " .
Alqamah narrates: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) performed the two prostrations of forgetfulness after saying the salam, and he had informed that the Noble Prophet (peace and blessings of Allah be upon him) also performed these two prostrations after saying the salam.
