Musannaf Ibn Abi Shaybah 3599 — What is recited in the Fajr prayer

Abu Abd al-Rahman said: I have not seen anyone more learned in the Qur'an than Sayyiduna Ali (may Allah be pleased with him). He led us in the Fajr prayer and recited Surah al-Anbiya' in it. When he had completed seventy verses, he left out a verse and recited the one after it. Then, when he remembered, he went back and recited it. Then he returned to the place he had been reciting from, and he did not falter at all.
