What does the Jewish/Christian Bible say about Prophet Muhammad (peace be upon him)?

Let the wilderness and its towns raise their voices; let the settlements where Kedar lives rejoice. Let the people of Sela sing for joy; let them shout from the mountaintops. Isaiah 42:11 NIV

Where is Sela? Right here in Madinah. What about Kedar?

These are the names of the sons of Ishmael, listed in the order of their birth: Nebaioth the firstborn of Ishmael, Kedar, Adbeel, Mibsam, Genesis 25:13 NIV

Reading Isaiah 42, you realize that Prophet Muhammad (peace be upon him) is prophesied.

“Here is my servant, whom I uphold, my chosen one in whom I delight; I will put my Spirit on him, and he will bring justice to the nations. Isaiah 42:1 NIV
