Abstract
This paper discusses the housing problem in Egypt which is due to the high prices of land and apartments. This problem affects all Egyptian families and consumes most of their income to cover rents and maintenance payments. This paper suggests the Islamic principle of Revivication (Ehyaa) as a way to solve this problem. Ehyaa permits any one to own any dead land by reviving it with building it, planting in it, dig a well in it, or any positive act which makes it more valuable or desirable. Reviver has to do so before Iimited time which differs according to site and circumstances, no one else can revive it during this period of time, but if it came to an end land becomes revivable again to anyone else. Ehyaa can motivate many people to build and settle down in the desert which forms more than 95% of Egypt's land, and will increase the urban space and makes the land free to use and inhabit
