أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ لاَ يُصَلِّي بَعْدَ الْجُمُعَةِ حَتَّى يَنْصَرِفَ فَيُصَلِّيَ رَكْعَتَيْنِ ‏.‏

It was narrated from Ibn 'Umar that:The Messenger of Allah (ﷺ) would not pray after Jumu'ah until he had left, then he would pray two rak'ahs. (Sahih)
