During the Subh prayer on Friday, the Messenger of Allah ﷺ used to recite: "Alif-Lam-Mim. The Revelation"(As-Sajdah 32) and: "Has there not been over man,"(Al-Insan 76) and in Jumu'ah prayer he would recite Al-Jumu'ah (62) and Al-Munafiqin (63). (Using translation from Nasāʾī 1421)
أَنَّ رَسُولَ اللهِ ﷺ «كَانَ يَقْرَأُ يَوْمَ الْجُمُعَةِ فِي صَلَاةِ الصُّبْحِ الم تَنْزِيلُ وَهَلْ أَتَى عَلَى الْإِنْسَانِ وَفِي صَلَاةِ الْجُمُعَةِ بِسُورَةِ الْجُمُعَةِ وَالْمُنَافِقِينَ»
