Sunan Ibn Majah, Volume 2, Book 5, Hadith 1130 (DarusSalam) ⓘ
It was narrated that when ‘Abdullah bin ‘Umar had prayed Friday, he went and prayed two Rak’ah in his house. Then he said: “The Messenger of Allah used to do that.”
حَدَّثَنَا مُحَمَّدُ بْنَ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ كَانَ إِذَا صَلَّى الْجُمُعَةَ انْصَرَفَ فَصَلَّى سَجْدَتَيْنِ فِي بَيْتِهِ ثُمَّ قَالَ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَصْنَعُ ذَلِكَ .
