Did Jesus Warn About Someone Like Muhammad?

In John 5:43, Jesus said something striking:

"I am come in my Father’s name, and ye receive me not: if another shall come in his own name, him ye will receive."

Jesus draws a clear contrast:

• He came in the Father’s name—representing God, speaking as His Son.
• Someone else would come in his own name—and people would accept him.

This raises an important question: Did Muhammad come in God’s name, or his own?

Muhammad's Letters and His Seal

When Muhammad sent letters to kings and emperors, he sealed them with a ring that read:
"Muhammad Rasul Allah"
(*Muhammad, Messenger of God*)

The purpose of the seal was clear:

• To show authority
• To verify the letter was from him
• To speak in his official capacity as a prophet, not privately

But this also means: He came in his own name.

Divine Authority ≠ Divine Content

Muhammad’s letters and sayings (Hadith) carried his prophetic authority, but the content was not considered divine revelation like the Quran.

He did not always say, *“Thus says the Lord”*. He spoke in his own words.

Contrast this with Jesus' prophecy in John 16:13:

"When he, the Spirit of truth, is come… he shall not speak of himself; but whatsoever he shall hear, that shall he speak."

This means:

• The true one will not speak from himself
• He will speak only what he hears from God
• He won’t come in his own name

The Verdict

Muhammad came:

• In his own name
• With a personal seal
• Speaking his own words in Hadith and letters
• Not saying “Thus says the Lord”

By Jesus’ standard in John 5:43, Muhammad fits the profile of the one who comes in his own name—not the one sent by the Father.

This is a personal theological reflection, not meant to offend or attack anyone’s beliefs.
