There are 1212 references in the Koran, to 'Reward' or Kabeen. In the Manichean view of the Moslem cult, the Moslems will receive the benefits of membership. The Infidel will simply be killed, humiliated, dominated by Moslems, or failing all of that, skewered to pieces by the Allah-thing in the after-life:

2:85 After this it is ye, the same people, who slay among yourselves, and banish a party of you from their homes; assist (Their enemies) against them, in guilt and rancour; and if they come to you as captives, ye ransom them, though it was not lawful for you to banish them. Then is it only a part of the Book that ye believe in, and do ye reject the rest? but what is the reward for those among you who behave like this but disgrace in this life? - and on the Day of Judgment they shall be consigned to the most grievous penalty. For God is not unmindful of what ye do.

The northern Arabian moon deity or El-Lah 'knows all that you do'. Or think. Or feel. Anything at all is the purview of this omnipotent dialectical force. If you reject even a small part of his program 'then is it only a part of the Book that ye believe in?'; you will face not only 'disgrace in this life', but also the 'most grievous penalty' in the after-life. What might that penalty be? Endless Oprah re-runs? Mandatory viewing of Hollywood 'comedies'? Jon Stewart day and night? BBC news for eternity? No the Allah punishment is thankfully not sadistic. It will simply kill you – over and over again – forever.

9:68 God hath promised the Hypocrites men and women, and the rejecters, of Faith, the fire of Hell: Therein shall they dwell: Sufficient is it for them: for them is the curse of God, and an enduring punishment, -

How tolerant and caring of the Moslems!! Anyone who rejects the moon cult is a 'hypocrite' and doomed to eternal punishment in Hell! Ah, that is exactly like the Golden rule found in Matthew 7:12........isn't it?

Even before you enter this hell-fire of Allah damnation, the Infidel Unbeliever who deigns not to follow the Muhammadan cult, might find himself transformed into an ape or pig in this life – this is another 'reward':

5:60 Say: "Shall I point out to you something much worse than this, (as judged) by the treatment it received from God? those who incurred the curse of God and His wrath, those of whom some He transformed into apes and swine, those who worshipped evil; - these are (many times) worse in rank, and far more astray from the even path!"

How loving of the Moslems. You must follow all of the diktats of Muhammad's cult. If you waver and do not follow the 'signs' of Islamic 'truth', you are declared to be 'evil' and open to Moslem predation and punishment, not to mention the wrath of the moon guy:

6:93 Who can be more wicked than one who inventeth a lie against God, or saith, "I have received inspiration," when he hath received none, or (again) who saith, "I can reveal the like of what God hath revealed"? If thou couldst but see how the wicked (do fare) in the flood of confusion at death! - the angels stretch forth their hands, (saying),"Yield up your souls: this day shall ye receive your reward, - a penalty of shame, for that ye used to tell lies against God, and scornfully to reject of His signs!"

and

7:40 To those who reject Our signs and treat them with arrogance, no opening will there be of the gates of heaven, nor will they enter the garden, until the camel can pass through the eye of the needle: Such is Our reward for those in sin.

Sin in Islam is simply rejecting the moon cult either in part or in its totality. If you sin in any way you are damned by Allah and will suffer hellish torment:

3:185 Every soul shall have a taste of death: And only on the Day of Judgment shall you be paid your full recompense. Only he who is saved far from the Fire and admitted to the Garden will have attained the object (of Life): For the life of this world is but goods and chattels of deception.

Life is thus about obeying the irrational cult of Muhammad. That is it really. No other deeds or actions need be undertaken. Follow the 'signs' of Allah and his Koranic theology and there is a good chance that you will be 'admitted to the Garden' of Moslem paradise in an after-life, which is the whole point of your worthless human existence. Non-Muslims are simply refused entry and punished.

Further the most faithful Moslems – the true Moslems – must fight and war in the cause of the El-Lah deity object. Not to do so is to imperil your after-life in the gardens of Moslem heaven. If you do fight [and die] in the cause of Islam, le paradis is assured:

4:74 Let those fight in the cause of God Who sell the life of this world for the hereafter. To him who fighteth in the cause of God, - whether he is slain or gets victory - Soon shall We give him a reward of great (value).

Die fighting for Allah and your great reward is eternity at his or its side in lush gardens overflowing with wine, women, food, and young boys [this doth seemeth to be a rather male-centric heaven doth it not?]. The Koran is truly an absurdity and a document of cultish supremacism laced with irrationality and racism. Kabeen or 'Reward' is yet another Koranic categorization dividing the world neatly between the great and good [the followers of the Allah-thing] and the rest who are unjust, unclean, miserable, evil, hypocritical and doomed to eternal hell.
