In fact, the term ‘Heaven’ has a shared meaning in Islam and all the other revealed religions. Primarily, it refers to that beautiful abode where, those who believe in only God, humble themselves to worship Him, do the good and avoid the evil, are promised to go after the end of this worldly life. In this sense, it is the synonym of the “Gardens of Paradise”, which is the equivalent of the Arabic word: Jannah. Those blessed dwellers will live there in an everlasting life.
This term, in Christian theology, may also mean a name of God the All Mighty. Again, in the sufist (mystic) tradition of both religions, this term means an ecstatic state of communion with God.
Thus, it is obvious that all the connotations of this word are spiritual and highly exalted, above the human level of worldly experience. It is a transcendental space that the believers, though never experienced, yet are able to conceive through the detailed description that God has supplied them with. This is in order to arouse their incitement and longing for it. It is difficult to quote the many verses in Quran that describe Heaven, as these are so many!
It might be sufficient to know that every pleasure in that Heaven is unparalleled to that in the worldly life. It is as the prophet of Islam, Muhammad (peace be upon him), described to enclose:
“What no eye has ever seen and no ear has never heard and no human heart has ever perceived.”
Its food, houses, rivers, pleasures… everything is beyond imagination! And because the believer is always attached to the spiritual more than the sensual, even in Heaven, God has made the ultimate ecstasy for the believers there, is to look at His Holy Countenance. Such is a blessing, from which believers never get bored or even get accustomed to, despite familiarity.
