If you're In Seventh Heaven you're truly delighted - over the moon and on cloud nine. According to Muslim belief there are seven heavens, each relating to one of the seven planets ruling the universe. It's suggested that every level of heaven consists of a precious stone or metal and that a servant of the Most High inhabits each one. The seventh heaven is the most glorious and is occupied by Abraham. Here, Abraham presides over everything and is the most loyal to God. During medieval times, the Cabbalists, Jewish mystics immersed in the occult, reinforced this conviction by interpreting the seventh heaven as the domain of God and his holy angels. Because of this, if you're "in seventh heaven" you're in a place of eternal bliss.
