Abu al-Hasan Muhammad bin Ishaq bin Rahawayh, the judge of Marw, said: My father was asked (about the Qur'an) while I was listening, and he said: "The Qur'an is the speech of Allah; it is His revelation and His knowledge, and it is not created." Sufyan bin Uyaynah narrates from Amr bin Dinar (may Allah have mercy on him): I found our shaykhs for seventy years, and they used to say this.
(b) Sufyan bin Uyaynah narrates from Amr bin Dinar (may Allah have mercy on him): I found the people for seventy years saying: Allah is the Creator, everything besides Him is created, and the Qur'an is the speech of Allah.
