Strike away from their saying that it is magic to the point that it is a mixture of dreams. Then to the point that it is a fabricated speech from him. Then to the point that it is the saying of a poet. And thus, falsehood is wavering. The saying 'falsehood is wavering' means that it is repeated without being exhausted. The one who invalidates is confused, returning and not firm on one statement.

It may be a revelation from Allah, glorified and exalted is He, regarding their words in the degrees of corruption. Their second saying is more corrupt than the first, and the third is more corrupt than the second, and likewise the fourth from the third. The correctness of the analogy in His saying 'as the earlier ones were sent' is from the perspective that it means: just as the earlier ones came with the signs. For the sending of the messengers entails coming with the signs. Do you not see that there is no difference between saying: 'Muhammad was sent' and saying: 'Muhammad came with the miracle'?
