Abu Imran relates that Sayyiduna Jundub (may Allah be pleased with him) said: "We were young boys with our Prophet (peace and blessings be upon him), and we learned faith before we learned the Qur'an. Then we learned the Qur'an, and through it our faith increased; whereas you people today learn the Qur'an before faith."
