in Edition Clear Qur'an by Talal Itani / Ibrahim (Abraham)

14:9Has not the story reached you, of those before you, the people of Noah, and Aad, and Thamood—and those after them? None knows them except God. Their messengers came to them with the clear proofs, but they tried to silence them, and said, “We reject what you are sent with, and we are in serious doubt regarding what you are calling us to.”

14:10Their messengers said, “Is there any doubt about God, Maker of the heavens and the earth? He calls you to forgive you your sins, and to defer you until a stated term.” They said, “You are only humans like us; you want to turn us away from what our ancestors worshiped; so bring us a clear proof.”
