To begin with it is ironic that any Muslim would appeal to what Satan, the greatest of all deceivers, quoted unsuccessfully in trying to tempt Jesus!
Yet again, CONTEXT is key! Psalms 91 is not specific to the Messiah, no does it reveal the Messiah’s titles, attributes and mission. Psalms 91 is God’s way of telling EVERYONE who believes in the true God of Abraham, Isaac and Jacob and seeks his divine protection will be saved from calamity and destruction. IT’S APPLICABLE TO ALL BELIEVERS.
“He who dwells in the secret place of the Most High Shall abide under the shadow of the Almighty. I will say of the Lord, “He is my refuge and my fortress; My God, in Him I will trust.” Psalms 91:1-2
In fact, in the same book, Psalm 22 is Jesus on the cross:
“My God, my God, why have you forsaken me? Why are you so far from saving me, so far from my cries of anguish? But I am a worm and not a man, scorned by everyone, despised by the people. All who see me mock me; they hurl insults, shaking their heads. “He trusts in the Lord,” they say, “let the Lord rescue him. Let him deliver him, since he delights in him.” Dogs surround me, a pack of villains encircles me; they pierce my hands and my feet. All my bones are on display; people stare and gloat over me. They divide my clothes among them and cast lots for my garment.” (Psalms 22:1, 6-8, 16-18)
Another chapter, Psalm 16, is a prophecy of the resurrection of Jesus from the grave:
“For you will not leave my soul among the dead or allow your holy one to rot in the grave.” Psalms 16:10
In the Law of Moses, the Prophets and the Psalms, the Messiah is variously prophecied as the “arm of the Lord”, (Isaiah 53) “the root of Jesse” (Isaiah 2 and 11), “the Branch” (Isaiah 2 and Jeremiah 33:15), “the Lord our Righteous Savior” (Jeremiah 33:16) “the Annointed” “the Messenger of the covenant” (Malachi 3:1) Ruler of Israel who is everlasting (Micah 5:2), “the ONE from the tribe of Judah to whom the obedience of the nations will be his” (Genesis 49:10), “son of man” who will be worshipped forever by the nations (Daniel 7:13-14), “son of God” (1 Chronicles 17:11-15) and Mighty God (Isaiah 9:6)
Which one of these titles and attributes MATCHES with the 7th century Isa of the Qur’an who is constructed from gnostic and heretical stories floating about in the 7th century?
