Musannaf Ibn Abi Shaybah 4872 — Those who permitted correcting

Ubaydah bin Rabi'ah said: I came to the Maqam of Ibrahim and there was a man in fine clothes with a pleasant fragrance standing and reciting the Qur'an in prayer. A man standing beside him was prompting him. I asked: Who is this? The people told me: It is Sayyiduna Uthman (may Allah be pleased with him).
