The first two come from the Crescent Project which is an interesting ministry to check out. Tom Doyle, author and traveler of the Middle East, tells many fascinating stories of the dreams of Jesus being had by Muslims all over the Middle East. Part 1 and Part 2 (mp3s). Listen to the first part of Part 2 and be amazed.
William Lane Craig recently spoke at a National Religious Broadcasters meeting on The Concept of God in Islam and Christianity (transcript and downloadable mp3s). Craig argues that the understanding of the Christian doctrine of the trinity as found in the Quran is mistaken-- it was Father, Son, Mary. He argues that the Christian doctrine of the trinity is rational and that the Muslim concept of God is rationally objectionable:
"I’d like to finish out my first point by offering an argument for why it is plausible to think that God is a Trinity. To begin with, God is by definition the greatest conceivable being. If you could conceive of anything greater than God then that would be God. Every Muslim who dies with the cry, “Allahu Akbar!” on his lips recognizes this point. God is the greatest being conceivable. Now, as the greatest conceivable being, God must be perfect. If there were any imperfection in God then he would not be the greatest conceivable being.A perfect being must be a loving being, for love is a moral perfection. It is better for a person to be loving than unloving. God, therefore, must be a perfectly loving being...
according to the Qur'an God’s love is reserved for the God-fearing and the good-doers; but he has no love for sinners and unbelievers. Thus, in the Islamic conception of God, God is not all-loving. His love is partial and has to be earned. The Muslim God only loves those who first love Him. His love thus rises no higher than the sort of love that Jesus said even tax-collectors and sinners exhibit."
