In all honesty, how could anyone really know the answer to this?
Read the Bible, then read the Koran. Then make a common-sense judgment as to the origin of each.
Also remember that Satan constantly tries to work opposite God's ways, in an effort to paint himself as God's counterpart. (He is not God's counterpart, because God doesn't have one. Satan is an angel, a wholly different and infinitely lower class of being who was created by God.)
The Bible paints a heaven based on intimacy with God. The Koran paints a heaven of orgies. The Bible teaches making peace whenever possible, teaches praying for one's enemies. The Koran teaches killing those who don't capitulate. And the contrasts go on and on and on. This is how you can know the answer.

Are you THAT limited in spiritual discernment???
Read the Bible and the Koran and Haddith. The difference between Islam and Christianity is clear. Christians will forgive. Muslims will kill.
Killing is the nature of Islam. That cannot be from God. Looks like an easy answer to me!
The example of Mohamed on forgivness Sahih Muslim, Book 17: 4206
There came to him (the Holy Prophet) a woman from Ghamid and said: Allah's Messenger, I have committed adultery, so purify me. He (the Holy Prophet) turned her away. On the following day she said: Allah's Messenger, Why do you turn me away? Perhaps, you turn me away as you turned away Ma'iz. By Allah, I have become pregnant. He said: Well, if you insist upon it, then go away until you give birth to (the child). When she was delivered she came with the child (wrapped) in a rag and said: Here is the child whom I have given birth to. He said: Go away and suckle him until you wean him. When she had weaned him, she came to him (the Holy Prophet) with the child who was holding a piece of bread in his hand. She said: Allah's Apostle, here is he as I have weaned him and he eats food. He (the Holy Prophet) entrusted the child to one of the Muslims and then pronounced punishment. And she was put in a ditch up to her chest and he commanded people and they stoned her. Khalid b Walid came forward with a stone which he flung at her head and there spurted blood on the face of Khalid and so he abused her. Allah's Apostle (may peace be upon him) heard his (Khalid's) curse that he had huried upon her. Thereupon he (the Holy Prophet) said: Khalid, be gentle. By Him in Whose Hand is my life, she has made such a repentance that even if a wrongful tax-collector were to repent, he would have been forgiven. Then giving command regarding her, he prayed over her and she was buried.
The example of Jesus on forgivness (John 8:1-11)
But Jesus went to the Mount of Olives. Early in the morning He came again into the temple, and all the people were coming to Him; and He sat down and began to teach them. The scribes and the Pharisees brought a woman caught in adultery, and having set her in the center of the court, they said to Him, "Teacher, this woman has been caught in adultery, in the very act. "Now in the Law Moses commanded us to stone such women; what then do You say?" They were saying this, testing Him, so that they might have grounds for accusing Him. But Jesus stooped down and with His finger wrote on the ground. But when they persisted in asking Him, He straightened up, and said to them, "He who is without sin among you, let him be the first to throw a stone at her." Again He stooped down and wrote on the ground. When they heard it, they began to go out one by one, beginning with the older ones, and He was left alone, and the woman, where she was, in the center of the court. Straightening up, Jesus said to her, "Woman, where are they? Did no one condemn you?" She said, "No one, Lord." And Jesus said, "I do not condemn you, either. Go. From now on sin no more."
