Muhammad was sent as a mercy to the worlds, which implies his prehuman existence and divinity.

The Quranic verses that refer to Muhammad as a mercy to the worlds (S. 21:107) highlight his role as a messenger, not as a divine being. In Christianity, Jesus is identified as the Word (Logos) who existed before creation, as stated in John 1:1-3. This establishes a clear distinction between the nature of Jesus and Muhammad. Furthermore, the assertion that Muhammad existed before creation lacks biblical support and contradicts the Christian doctrine of the Trinity, where Jesus is eternally begotten, not created. The concept of mercy in the Quran does not imply divinity; rather, it reflects God's compassion towards humanity, which is fully realized in Jesus Christ, who embodies God's mercy through His sacrificial love on the cross.
