I’m going to explain it to you.

Mohamed was a false prophet. His name is attached to the document the Quran. This document is, as a result, a document of hubris.

Here are some lines in the Quran:

Surah 3:151: “We shall cast terror into the hearts of those who disbelieve (all non-Muslims) ...”

Surah 2:191: “And kill them (non-Muslims) wherever you find them ... kill them. Such is the recompense of the disbelievers (non-Muslims).”

Surah 9:5: “Then kill the disbelievers (non-Muslims) wherever you find them, capture them and besiege them, and lie in wait for them in each and every ambush ...”

…so, since this person Mohamed is using the authority of God to speak, and is additionally a “non-believer.” The words will be directed against him. If you preach hate and death in God’s name, what would be more just?
