Zuhayr ibn Harb, ʿUbaydullah ibn Saʿid, and Muhammad ibn al-Muthanna narrated to me, all of them from Yahya al-Qattan — Zuhayr said: Yahya ibn Saʿid narrated to us — from ʿUbaydullah, who said: Nafiʿ informed me, from Ibn ʿUmar, that the Prophet, peace and blessings be upon him, used to recite the Qur'an, and he would recite a surah containing a prostration, and he would prostrate, and we would prostrate with him, until some of us could not find a place for his forehead.
