Another class of technical terms are those which the Ṣúfís employ, without metaphor, in unification (tawḥíd) and in setting forth their firm belief in spiritual realities.
`Álam. The term `álam (world) denotes the creatures of God. It is said that there are 18,000 or 50,000 worlds. Philosophers say there are two worlds, an upper and a lower, while theologians say that `álam is whatever exists between the Throne of God and the earth. In short, `álam is the collective mass of created things. The Ṣúfís speak of the world of spirits (arwáḥ) and the world of souls (nufús), but they do not mean the same thing as the philosophers. What they mean is “the collective mass of spirits and souls”.
