Al-'Ankabut · 29:51

51. O Messenger! Is it not sufficient for these people who propose miracles, that we have revealed the Qur’ān upon you which it recited to them? Indeed, in the Qur’ān is mercy and exhortation to believing people, because they are the ones who truly benefit from whatever it contains. Therefore, whatever has been revealed to them is better than that which they suggest should be sent down: similar to what was sent to Messengers previously.
