1688 - Abu Bakr informed us, saying: Isma'il ibn Abi Karima narrated to us, saying: I heard Yazid ibn Harun say: 'The Qur'an is the speech of Allah. May Allah curse Jahm and whoever follows his doctrine; he was a disbeliever and a denier who abandoned prayer for forty days, claiming he was seeking a religion, when in fact he was in doubt about Islam.'
