A Momin who will enter Jannah will get uncountable great rewards in
Jannah (Heaven) by the Allah SWT for the good deeds that he done in this
world. One of the great reward that men will get in heaven are hoors
beautiful women of Heaven.
Allah SWT has said in Quran those who done good deeds will have great success in hereafter. They will get Gardens and women of same age. Quranic verse says Verily, We have created them (maidens) of special creation. And made them virgins; Loving (their husbands only), equal in age.
According to a Hadith Hoors of Paradise will be pure women free of menstruation, urine, stool, cough and children. The Hoors will sing in Paradise on divine purity and praise. we are most beautiful Hoors and we are for the honored husbands.
There are many qualities of the hoors that are told in Quran and Hadith for example:
Hoors will be much more beautiful than women of this world.
They will be pure women who keeps their eyes low and will only see their husbands.
Hoors are not touched by any men before.
Hoors will be having good character and qualities
Hoors will have beautiful big eyes.
Wives of this world will also become hoors for their husbands in heaven.
Hoors will obey orders of their husbands.
These are some of the qualities that Hoors will be having in paradise. Even a man who will enter in paradise will minimum good deeds will get at least 72 hoors.
From these hadiths we can understand how big reward Hoors will be for a Momin in the paradise. But we should also remember that we will get this great reward only if we will do good deeds and obey Allah SWT in this world.
