Musannaf Ibn Abi Shayba 22:150

Ibn Idris narrated to us, from Isma'il, from al-Sha'bi, who said: The reciters of the Quran during the era of the Prophet, peace and blessings of Allah be upon him, were Ubayy, Mu'adh, Zayd, Abu Zayd, Abu al-Darda', and Sa'id ibn 'Ubayd. None of the Caliphs among the companions of the Prophet, peace and blessings of Allah be upon him, recited it [the entire Quran] except 'Uthman. And Mujammi' ibn Jariyah recited it, except for a surah or two.
