10:15And when Our clear revelations are recited to them, those who do not hope to meet Us say, “Bring a Quran other than this, or change it.” Say, “It is not for me to change it of my own accord. I only follow what is revealed to me. I fear, if I disobeyed my Lord, the torment of a terrible Day.”

10:16Say, “Had God willed, I would not have recited it to you, and He would not have made it known to you. I have lived among you for a lifetime before it. Do you not understand?”

10:61You do not get into any situation, nor do you recite any Quran, nor do you do anything, but We are watching over you as you undertake it. Not even the weight of an atom, on earth or in the sky, escapes your Lord, nor is there anything smaller or larger, but is in a clear record.
