Islam does not mean “peace”.
No matter how many times it gets repeated, do not believe anyone who tells you that Islam is derived from the word “salam” meaning peace.
Islam is derived from the word “aslama” which means “surrender” or “submission.”
Anyone telling you differently is trying to obfuscate. Ask a Muslim what Islam means. If they are being honest, they will tell you “submission to God.” Any other answer is to confuse you.
