Paradise in Islam

Islam accepts the existence of paradise where religious people will get after death requital. According to the Koran god created something that people never heard, never saw and never dreamed of.
The paradise is described as the gardens with the rivers. The trees of the garden have a lot of fruits with different tastes. Every person has the second half in this paradise. For example, the man has the wife and the woman has the husband. And the second half has absolutely pure body and soul. They are kind, ideal without any troubles and defects. And people will live there for eternity.
According to Islam, righteous men will live with their "houri" – black eyed full-bosomed virgin that becomes virgin every morning.
The righteous men will be dressed in green silk, atlas and other precious textiles and will have rest on the green pillows in the certain marquee of saint sizes made of pearls and other precious stones. And young men dressed in green clothes with silver decorations will serve them.
It is also mentioned that all inhabitants of paradise will drink the wine from which they won't get drunk. There won't be natural defecations everything will come from the person with the help of skin.
Islam also mentions the existence of Eden that was the earth paradise as well as the idea of four rivers in it.
