Islamic Folklore The Price of House In Al-Jannah Paradise English Edition [EPUB ebook] 

"There were two men who were partners and had collected eight thousand Dinars. One of them had a craft and the other did not. The one who had a craft said to the other, 'You do not have a craft, so I think I will divide the money with you and leave you.’ So he left him.Then the first man bought a house, belonging to a king who had died, for the price of one thousand Dinars. He called his companion and showed him the house saying, What do you think of this house I bought it for one thousand Dinars. He said, How beautiful it is. When he went out he said, O Ya Allah SWT, this companion of mine has bought this house for one thousand Dinars; I ask You for one of the houses of Jannah Paradise and he gave one thousand Dinars in charity.
