In Islamic eschatology, Jannah refers to the garden of Paradise, a place where righteous Muslims will be sent as an eternal reward for good behaviour in the mortal life.
Jannah should be rendered into English as ‘Paradise’ and not ‘Heaven’, as the concept of heaven in Islam is different.

In the Quran, Jannah is described as a place of eternal happiness, as well as the ultimate satisfaction of living in Allah’s company.
