In Islam, Jannah, lit. "paradise, garden", is the final abode of the righteous and the Islamic believers, but also the Garden of Eden, where Adam and Hawa dwelt is also called Jannah. Firdaus is the literal term meaning paradise which was borrowed from the Persian word Pardis, being also the source of the English word 'paradise', but the Quran generally uses the term Jannah symbolically referring to paradise. However "Firdaus" also designates the highest level of heaven.
