What Bible says about Islam?

Many Christians having good opinion on Islam, because Islam do speak about the prophets of the Bible, for example they call Abraham as Ibrahim, and Moses as Musa, and David as Dawud, but they preach another Jesus who did not suffer on the cross, Is that ok? denying Christ's death is not denying God's love towards us? but God shows his love for us in that while we were still sinners, Christ died for us - Romans 5:8

Once Apostle Peter told the same idea of Islam to Jesus Christ "Far be it from you, Lord! This shall never happen to you", and Christ response to the peter "Get behind me, Satan!" is tells that from where the Islam is originated - 21.From that time Jesus began to show his disciples that he must go to Jerusalem and suffer many things from the elders and chief priests and scribes, and be killed, and on the third day be raised. 22.And Peter took him aside and began to rebuke him, saying, Far be it from you, Lord! This shall never happen to you. 23.But he turned and said to Peter, “Get behind me, Satan! You are a hindrance to me. For you are not setting your mind on the things of God, but on the things of man - Matthew 16:21-23

Why the Spirit of God wrote Apostle Peter's proposal in the Bible that Jesus Christ not required to die on the cross? for just one reason that people should understand the dangerous of Islam, in addition to that, Apostle Paul mentioned Islam's Jesus as another Jesus, Because the original purpose of Jesus Christ came into this world is to redeem us by his blood so that we can have eternal life, and diverting the people to eternal hell is a craftiness of serpent - 3.But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. 4.For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted - you may well put up with it! - 2 Corinthians 11:3-4 

And Apostle Paul is very sure that people will rise like a wolves that will not spare the flock, so 500 years before the birth of prophet Muhammad He wrote this - 29.I know that after my departure fierce wolves will come in among you, not sparing the flock; 30.and from among your own selves will arise men speaking twisted things, to draw away the disciples after them - Acts 20:29-30

And there used to be a Beautiful Temple in Jerusalem, and when people of Jerusalem did not accept Jesus Christ, He said that this House will become desolate place, its like bottle of milk turning into deadliest poison anyone who consumes will die, and if you go Jerusalem and look at the place you will see a Masque standing as a symbol of desolate - O Jerusalem, Jerusalem, the city that kills the prophets and stones those who are sent to it! How often would I have gathered your children together as a hen gathers her brood under her wings, and you were not willing! See, your house is left to you desolate - Matthew 23:37-38

So what is standing over the rock of dome is a desolation, the word desolate is used for referring deadly deserts where people will starve to death, this tells the dangerous of Islam which leads many into eternal hell, so 1000 years before building the dome of rock, Apostle Paul wrote this - for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children - Galatians 4:25
