The Brain, The Koran is the concoction of Mohammed to motivate his followers (with all those rewards in Paradise, cruel punishment in hell, etc). The poor fellow could think of wine, woman, water, fruits, etc even in the "Paradise"
There is no soul, no re-birth and no "last judgement" Every thing ends here. So enjoy life on planet earth to the extent possible without harming others for rewards in an imaginary life "here-after"
