Heaven in Islam
is described in the Qur'an as an eternal afterlife of peace and bliss, where the faithful and righteous are rewarded. They will be restful in the presence of Allah, in "gardens beneath which rivers flow." Jannah comes from an Arabic word which means "to cover or hide something." Heaven, therefore, is a place which is unseen to us.
The Quran describes that Jannah is "...a beautiful place of final return – a garden of eternity, whose doors will always be open to them" [38:49-50].
