Christianity teaches that God loves all men, but hates sin. The Qur’an never says this. Instead it explicitly declares that Allah does not love those who do not believe in him:
For
He loves not those who reject Faith (30:45)
Allah only loves those who obey Muhammad (at least according to Muhammad):
Say: "Obey Allah and His Messenger": But if they turn back, Allah
loveth not those who reject Faith. (3:32)
Whereas Christianity teaches that God loves the sinner, but hates sin, the wrath of Islam's god is placed squarely on the person:
Surely Allah
does not love any one who is unfaithful, ungrateful. (22:38)
Verses 11:118-199 say that Allah does not bestow mercy on everyone. For this reason, he chooses not to guide some people:
And Allah's is the direction of the way, and some (roads) go not straight. And had He willed He would have led you all aright. (16:9)
For those whom Allah does not love, there will be the most terrible of eternal torments:
Those who reject our Signs, We shall soon cast into the Fire: as often as their skins are roasted through, We shall change them for fresh skins, that they may taste the penalty: for Allah is Exalted in Power, Wise. (4:56)
As we can see, Allah hates unbelievers so much that he even leads them into sinning and actively prevents them from believing in him, thus ensuring their fate.
