A call from God to Jews and Christians
God - be glorified - sent Prophet Mohammed to the idolaters: the Arab and to Jews and Christians: the people of the Bible: because they distorted the basic Commandments and concealed many statements in the Torah and the Gospel which they did not apply.. so God sent Mohammed to be an argument against them, in order that they will not say on Judgment Day: God, You did not send us any messenger to give us the good news for our obedience and to warn us against our disobedience so that we could have avoided that disobedience.
