There is a reason why we claim that God of the Scripture and Allah from the Qu'ran are not the same God...and I'm a Christian so you already know that I believe only one exist...
Here is one of the biggest contradictions between the two:
Matthew 3:13-17
13 Then Jesus came from Galilee to John at the Jordan to be baptized by him. 14 And John tried to prevent Him, saying, I need to be baptized by You, and are You coming to me?
15 But Jesus answered and said to him, Permit it to be so now, for thus it is fitting for us to fulfill all righteousness. Then he allowed Him.
16 When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. 17 And suddenly a voice came from heaven, saying, This is My beloved Son, in whom I am well pleased.
The Qu'ran claims:
Pretty contradictory don't you think?
One God claim that He has a Son and one claims that if one say that he has a Son it is considered blasphemy and that those who say it is admonish".
For the Christian, this is our confession:
1 John 4:12-16
12 No one has seen God at any time. If we love one another, God abides in us, and His love has been perfected in us. 13 By this we know that we abide in Him, and He in us, because He has given us of His Spirit. 14 And we have seen and testify that the Father has sent the Son as Savior of the world. 15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16 And we have known and believed the love that God has for us. God is love, and he who abides in love abides in God, and God in him.
John 3:16
"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have eternal life. 17For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. 18 He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
There is no way to mistake the matter. The Qu'ran has other verses that claim that it is blasphemy if we claim that Jesus is the Son of God, but the Scripture tells us that if we don't believe that Jesus is the Son of God that we are condemned already. I'll side with the God of the Scripture.
