"They shall recline on jewelled couches face to face, and there shall wait on them immortal youths with bowls and ewers and a cup of purest wine (that will neither pain their heads nor take away their reason); with fruits of their own choice and flesh of fowls that they relish. And theirs shall be the dark-eyed houris, chaste as hidden pearls: a guerdon for their deeds... We created the houris and made them virgins, loving companions for those on the right hand..."
Surah-al-rehman 55:272
'The smallest reward for the people of paradise is an abode where there are 80,000 servants and 72 wives, over which stands a dome decorated with pearls, aquamarine, and ruby, as wide as the distance from Al-Jabiyyah [a Damascus suburb] to Sana'a [Yemen]'."
Al-Suyuti
Each time we sleep with a houri we find her virgin. Besides, the penis of the Elected never softens. The erection is eternal; the sensation that you feel each time you make love is utterly delicious and out of this world and were you to experience it in this world you would faint. Each chosen one [ie Muslim] will marry seventy [sic] houris, besides the women he married on earth, and all will have appetising vaginas."
