Zuhayr ibn Harb narrated to me: Waki' narrated to us, from Sufyan, from Sa'd ibn Ibrahim, from 'Abd al-Rahman al-A'raj, from Abu Hurayrah, from the Prophet, peace and blessings be upon him, that he used to recite in the dawn prayer on Friday: "Alif Lam Mim. The Revelation" (al-Sajdah) and "Has there come upon man" (al-Insan).
