Muhammad, a plain warner

Then do they not give thought? There is in their companion [i.e., Muḥammad (ﷺ)] no madness. He is not but a clear warner.

Say, "I hold not for myself [the power of] benefit or harm, except what Allāh has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe."

[Through a messenger, saying], "Do not worship except Allāh. Indeed, I am to you from Him a warner and a bringer of good tidings,"

And say, "Indeed, I am the clear warner" -

This [Prophet (ﷺ)] is a warner from [i.e., like] the former warners.
