Anyone who does not abide(live) in the doctrine of Christ (new testament) does not have the right God.
[2Jo 1:8-11
8 Look to yourselves, that we do not lose those things we worked for, but [that] we may receive a full reward.
9 Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son.
10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him;
11 for he who greets him shares in his evil deeds.
Sharia is the muslims law. The same as the Torah.
