We as Muslims believe that Allah (God) doesn’t beget and is not begotten. If Jesus is god, he can’t be born and he can’t die. How can he die for our sins and all the Prophets and Messengers before him had never mentioned that Allah has a son and that he would die for our sins? If you have 10 boys, one is good and the rest are evil. Would it be fair to punish the good boy for the sins of the other 9? Can it be that nowhere in the Bible where Jesus, the so claimed son of god doesn’t tell people to worship him? This is the clearest evidence that he is not a god or a son of god.
