The beautiful dark-eyed virgins called houris are believed by some Muslims to be waiting in heaven (Muslim Paradise) just for the pleasure of the faithful.
Faithful, as in the ones that have died martyrs. These houris, according to the Qu'ran (55.56) have never been touched by man, nor (jinni) a supernatural spirit, lesser than a demon or an angel.
Terrorists that martyr themselves in the name of Muhammad believe they will gain instant entry in Muslim Paradise and will enjoy a sensuous afterlife with the many houris, based on a hadith collected by Imam at-Tirmidhi in "Sunan" (vol. 4, chapters on "The Features of Heaven as described by the Messenger of Allah," chapter 21, "About the Smallest Reward for the People of Heaven," hadith 2687) It is also quoted by Ibn Kathir in his Tafsir (Koranic commentary) of Surah Rhman (55), ayah (verse) 72:
I don't want to confuse anyone but here goes:
Someone said, that he overheard someone talking to someone else, that he heard that the Prophet Muhammand said to one of these martyrs:
"The smallest reward for the people of Heaven is an abode where there are eighty thousand servants and seventy-two wives, over which stands a dome decorated with pearls, aquamarine and ruby, as wide as the distance from al-Jabiyyah to An'a."
Where ever, that is!
I know this sounds like gossip to the third degree, but it wasn't just meant for martyrs, it was meant for the general public.
It's the weird ones, the fanatics, the crazy persons, the terrorists that interpret what Muhammand said, to mean that committing murder or suicide for Islam will automatically put them to the front of the line. That they will be the ones who will benefit, having many servants and oh yes, many many houris.
