Nafi' reported that when 'Abdullah (b. 'Umar) observed the Friday prayer and came back he observed two rak'ahs in his house, and then said: The Messenger of Allah (may peace be updn him) used to do this.
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَمُحَمَّدُ بْنُ رُمْحٍ، قَالاَ أَخْبَرَنَا اللَّيْثُ، ح وَحَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا لَيْثٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ، أَنَّهُ كَانَ إِذَا صَلَّى الْجُمُعَةَ انْصَرَفَ فَسَجَدَ سَجْدَتَيْنِ فِي بَيْتِهِ ثُمَّ قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصْنَعُ ذَلِكَ .
