Paradise is another name for eternal life in the neighbourhood of God (66:11). Paradise is the eternal ideal world, which is the ultimate objective of every human. Paradise is called the 'Home of Peace' (10: 25). We learn from the Quran that the people of Paradise will wish peace for one another, which indicates the importance of peace in the ideal society. In the world before death, those who live in the neighbourhood of God at the psychological level and feeling will, in the world Hereafter, live in the eternal neighbourhood of God—Paradise—in reality.

The good fortune of finding a place in God's neighbourhood in the eternal life of the Hereafter will be based totally on merit. God's neighbourhood is like a universal garden. Only those will find a place in this universal garden that measure up to the divine criterion. Anything short of this will not guarantee a place in this universal garden.
