Mohammed knew that sex would sell very well among the group of his lecherous followers who were motivated to fight battles by the promise of sex slaves and booty. Once the followers got to heaven, they could pleasure themselves with endless sexual encounters with 'Houris' (beautiful young virgins)... 72 virgins girls and 28 young pre-pubescent boys. Mohammed goes one step further and expands the promise of virgins to include a free sex market where there is no limit of the number of sexual partners. Women and young boys are on display as if in a fruit market where you can choose the desired ripeness. Allah is indeed merciful!
