Jesus can raise the dead, why not call him to come down from heaven to raise Muhammad from the grave. Then we can all make thousands of questions for proof.
We dont have to do that to know Islam is false, its actually really easy to disprove Islam is false.
Islam claims that no one can change allahs word-
Quran 18:27 "And recite what has been revealed to you of the book of your lord, there is none who can alter his words; and you shall not find any refuge besides him"
Islam also claims that the Gospel and torah come from him as well-
Quran 3:3-4 "He has revealed to you the book with truth, verifying that which is before it, and he revealed the torah and the Gosple aforetime, a guidance for mankind, and he revealed the criterion."
And he even tells us Christians to judge Islam by the Gospel, that if we do not do so, we are just as bad as the unbelievers-
Quran 5:47 "Let the people of the Gospel judge by what allah hath reveled therein. If any do fail to judge by (the light of) what allah hath revealed, they are (no better than) those who rebel."
If you know what Islam teaches, you know that it tells you Christ was no more than a messenger, that allah has no son, and that Christ did not die on the cross for our sins.
If you know what the Gospel teaches, Christ called Himself the Son of God, who existed with God before the world ever existed, who would be the judge on the last day, who came to die for our sins, and that He is the "Good Shepherd".
So, if I as a Christian am to judge Islam by the Gospel, it is obvious that Muhammad was a false prophet : p
Luckily, the Bible already covered this in 1 John 2:22.
