Sunan an-Nasai
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا جَرِيرٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا صَلَّى أَحَدُكُمُ الْجُمُعَةَ فَلْيُصَلِّ بَعْدَهَا أَرْبَعًا " .
It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'When any one of you prays Jumu'ah let him pray four (rak'ahs) after that.'"
