Musannaf Ibn Abi Shayba 27:51

Ibn ‘Uyaynah narrated to us, from Ibn Abi Najih, from Mujahid: “And indeed, it is a remembrance for you and your people, and you will be questioned.” He said: It is said, “From whom is this man?” He says, “From the Arabs.” It is said, “From which of the Arabs?” He says, “From Quraysh.” “And We raised high for you your remembrance.” He said: I am not mentioned except that you are mentioned: “I bear witness that there is no god but Allah, and I bear witness that Muhammad is the Messenger of Allah.”
