Quran 33:39 — The Parties (Al-Ahzab)

Those who deliver GOD's messages, and who reverence Him alone, shall never fear anyone but GOD. GOD is the most efficient reckoner.

[33:38] The prophet is not committing an error by doing anything that is made lawful by GOD. Such is GOD's system since the early generations. GOD's command is a sacred duty.

[33:40] Muhammad was not the father of any man among you. He was a messenger of GOD and the final prophet. GOD is fully aware of all things.
