and manifold; hence the evidences of its inimitability come in many forms, the facets of its miraculous nature are diverse, and every single facet, taken on its own, attests to that inimitability.

To expand upon these points would require a lengthy exposition. For this reason the Exalted has said:

“They say, ‘Why have no signs been sent down to him from his Lord?’ Say: ‘The signs are with Allah alone; I am only a clear warner.’ Is it not enough for them that We have sent down to you the Book, which is recited to them? Surely in this there is mercy and a reminder for a people who believe.” (29:50)

Thus, the Qur’an is sufficient both for the call and for clarification; it is sufficient as proof and conclusive evidence.
