The Prophet ﷺ used to recite the following in the Fajr prayer of Friday, "Alif, Lam, Mim, Tanzil" (Suratas- Sajda #32) and "Hal-ata-ala-l-Insani" (i.e. Surah-Ad-Dahr #76). (Using translation from Bukhārī 891)
كَانَ النَّبِيُّ ﷺ «يَقْرَأُ يَوْمَ الْجُمُعَةِ فِي صَلَاةِ الْفَجْرِ الْم تَنْزِيلُ السَّجْدَةَ وَهَلْ أَتَى عَلَى الْإِنْسَانِ»
