Challenge of the Qur'an ( 10 : _ 37 39)

And it was not [possible] for this QurÕŒn to be produced by other than Allah, but [it is] a confirmation of what was before it and a detailed explanation of the [former] Scripture, about which there is no doubt,from the Lord of the worlds.

Or do they say [about the Prophet ], "He invented it?" Say, "Then bring forth a s´rah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful."
Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers.
