'Ata said: When Ibn 'Umar offered the Friday prayer in Mecca he would go forward and pray two rak'ahs, he would then go forward and pray four rak'ahs; but when he was in Medina, he offered the Friday prayer, then returned to his house and prayed two rak'ahs, not praying them in the mosque. Someone mentioned this to him and he replied that the Messenger of Allah (ﷺ) used to do it.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ بْنِ أَبِي رِزْمَةَ الْمَرْوَزِيُّ، أَخْبَرَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ عَبْدِ الْحَمِيدِ بْنِ جَعْفَرٍ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ عَطَاءٍ، عَنِ ابْنِ عُمَرَ، قَالَ كَانَ إِذَا كَانَ بِمَكَّةَ فَصَلَّى الْجُمُعَةَ تَقَدَّمَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ تَقَدَّمَ فَصَلَّى أَرْبَعًا وَإِذَا كَانَ بِالْمَدِينَةِ صَلَّى الْجُمُعَةَ ثُمَّ رَجَعَ إِلَى بَيْتِهِ فَصَلَّى رَكْعَتَيْنِ وَلَمْ يُصَلِّ فِي الْمَسْجِدِ فَقِيلَ لَهُ فَقَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَفْعَلُ ذَلِكَ .
