Karahah sometimes spelled Kariha in the Koran, means 'hate', 'dislike' or 'averse to'. It is used in connection with the Unbelievers or those who reject Muhammad's commands and leadership. First, Moslems might not like fighting the Infidel but Allah wills them to do it. Remember humans have no free-will in Islam, only the Al-Lah moon deity possesses free-will. Second, Unbelievers must be fought since they 'hate' Muhammad's cult. Third, the Infidels are 'averse to' and quite 'dislike' the diktats of the El-Lah thing, and must be brought into line through coercion and intractable purpose. The Arabic word for hate permeates all sections of the Koran.

Al-Lah wills you to fight for him [or it]

2:216 Jihad (holy fighting in Allah's Cause) is ordained for you (Muslims) though you dislike it, and it may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allah knows but you do not know.

58:8 Have you not seen those who were forbidden to hold secret counsels, and afterwards returned to that which they had been forbidden, and conspired together for sin and wrong doing and disobedience to the Messenger (Muhammad SAW). And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say?" Hell will be sufficient for them, they will burn therein, and worst indeed is that destination!

61:9 He it is Who has sent His Messenger (Muhammad SAW) with guidance and the religion of truth (Islamic Monotheism) to make it victorious over all (other) religions even though the Mushrikun (polytheists, pagans, idolaters, and disbelievers in the Oneness of Allah and in His Messenger Muhammed SAW) hate (it).

10:82 "And Allah will establish and make apparent the truth by His Words, however much the Mujrimun (criminals, disbelievers, polytheists, sinners, etc.) may hate it."

As the above relate the Al-Lah thing is no friend of the Unbeliever. He or it, is also quite upset by the fact that Jews and Christians are stubbornly stupid, and refuse to accept Muhammad as a 'prophet' or agent of religiosity. For that they must also go to Hell.

Unbelievers 'hate' the Muhammadan cult and must be punished

23:70 Or say they: "There is madness in him? [Muhammad]" Nay, but he brought them the truth [i.e. "(A) Tauhid: Worshipping Allah Alone in all aspects (B) The Qur'an (C) The religion of Islam,"] but most of them (the disbelievers) are averse to the truth.
43:78 Indeed We have brought the truth (Muhammad SAW with the Qur'an), to you, but most of you have a hatred for the truth.

61:9 He it is Who has sent His Messenger (Muhammad SAW) with guidance and the religion of truth (Islamic Monotheism) to make it victorious over all (other) religions even though the Mushrikun (polytheists, pagans, idolaters, and disbelievers in the Oneness of Allah and in His Messenger Muhammed SAW) hate (it).

Worse still many not only reject the adventurer Muhammad, but also Al-Lah itself. This is simply unacceptable to the moon idol's sense of universal order.

Unbelievers reject the El-Lah idol [a sin]

5:59 Say: "O people of the Scripture (Jews and Christians)! Do you criticize us for no other reason than that we believe in Allah, and in (the revelation) which has been sent down to us and in that which has been sent down before (us), and that most of you are Fasiqun [rebellious and disobedient (to Allah)]?"

8:8 That He might cause the truth to triumph and bring falsehood to nothing, even though the Mujrimun (disbelievers, polytheists, sinners, criminals, etc.) hate it.

9:32 They (the disbelievers, the Jews and the Christians) want to extinguish Allah's Light (with which Muhammad SAW has been sent - Islamic Monotheism) with their mouths, but Allah will not allow except that His Light should be perfected even though the Kafirun (disbelievers) hate (it).

16:62 They assign to Allah that which they dislike (for themselves), and their tongues assert the falsehood that the better things will be theirs. No doubt for them is the Fire, and they will be the first to be hastened on into it, and left there neglected.

47:26 This is because they said to those who hate what Allah has sent down: "We will obey you in part of the matter," but Allah knows their secrets.

Hate, the fire, fighting.....There are no corollaries to the above in the New Testament. The intent of the word 'hate' is clear within the Koran. The Unbelievers 'hate' Muhammad, Islam and the Al-Lah thing and deity. This actually may or may not be true. It certainly would not be valid in all cases. But the important theme is to persuade the cult's followers that the Jews and Christians 'hate' them, are their enemies, and perforce need to be vanquished. This makes violence against non-Moslems all the much easier and more acceptable.
