Is the current arrangement of the surahs in the mushaf divinely ordained or not?

The questioner : This question reminds me of another question, which is: Is the current arrangement of the surahs in the mushaf divinely ordained or not?

The Shaykh : It is a matter of scholarly disagreement. There is no doubt that the arrangement of the verses within the surahs is divinely ordained. As for the surahs themselves in this order, is it divinely ordained from the Messenger (peace and blessings be upon him) or is it independent legal reasoning? I have no definitive opinion on this matter; Allah knows best.
