Heaven:
Originally the term "heaven" referred to the sky or the area above the earth where the "heavenly bodies" are placed. This is the main meaning of the word in the Bible. It was considered the dwelling place of God and his angels. However, with time, the term came to be used also in the sense of the abode of the righteous at some point after death. This is supported by a few verses in the Bible, but the Bible tends to use other terms, such as Paradise, for this. (See below for other terms.)

Hell:
Hell, according to many religious beliefs, is an afterlife of suffering where the wicked or unrighteous dead are punished. Hell is almost always depicted as underground. Within Islam hell is traditionally depicted as fiery. Some other traditions, however, portray Hell as cold and gloomy. Punishment in Hell typically corresponds to sins committed in life.
