"And when Our clear messages are recited to them, those who have no hope of meeting with Us say: Bring a Qur'an other than this or change it. Say: It is not for me to change it of my own accord. I follow naught but what is revealed to me. Indeed I fear, if I disobey my Lord, the chastisement of a grievous day. Say: If Allah had desired, I would not have recited it to you, nor would He have made it known to you. I have lived among you a lifetime before it. Do you not then understand?"
