Christianity teaches that God loves all people, but hates sin. The Koran never says that. Instead, it explicitly states that Allah does not love those who do not believe in Him:
That He may reward those who believe (in the Oneness of Allah Islamic Monotheism), and do righteous good deeds, out of His Bounty. Verily, He likes not the disbelievers. (30:45)
Allah loves only those who obey Muhammad (at least according to the "narrative" of Muhammad):
Say (O Muhammad): "Obey Allah and the Messenger (Muhammad)." But if they turn away, then Allah does not like the disbelievers. (3:32)
Instead of a god who loves the sinner even if he hates sin, the wrath of Allah is laid upon the individual:
Truly, Allah defends those who believe. Verily! Allah likes not any treacherous ingrate to Allah [those who disobey Allah but obey Shaitan (Satan)]. (22:38)
Some verses say that Allah does not give grace to everyone. For this reason he gives some people no guidance:
And upon Allah is the responsibility to explain the Straight Path (i.e. Islamic Monotheism for mankind i.e. to show them legal and illegal, good and evil things, etc. so, whosoever accepts the guidance, it will be for his own benefit and whosoever goes astray, it will be for his own destruction), but there are ways that turn aside (such as Paganism, Judaism, Christianity, etc.). And had He willed, He would have guided you all (mankind). (16:9)
In fact, he instructs Satan to lead the unbelievers into the destruction:
"And Istafziz [literally means: befool them gradually] those whom you can among them with your voice (i.e. songs, music, and any other call for Allah's disobedience), make assaults on them with your cavalry and your infantry, mutually share with them wealth and children (by tempting them to earn money by illegal ways usury, etc., or by committing illegal sexual intercourse, etc.), and make promises to them." But Satan promises them nothing but deceit. (17:64)
For those who do not love Allah, there will be the most terrible eternal torments, including eternal roasting:
Surely! Those who disbelieved in Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) We shall burn them in Fire. As often as their skins are roasted through, We shall change them for other skins that they may taste the punishment. Truly, Allah is Ever Most Powerful, All-Wise. (4:56)
"Allah is the enemy of the unbelievers" (2:98), and as we shall see, he hates them so much that he even leads them into sin and then actively prevents them from believing in him and thus facilitating their fate .
