Sufi cosmology () is a Sufi approach to cosmology which discusses the creation of man and the universe, which according to mystics are the fundamental grounds upon which Islamic religious universe is based. According to Sufi cosmology, God's reason for the creation of this cosmos and humankind is the "manifestation" and "recognition" of Himself as it is stated in Hadith Qudsi – "I was a hidden Treasure; I desired to be recognized so I created the creature". Emanation Islamic Sufis describe the Divine Descent and the creation of universe and humankind in the following stages, when Noor-e-Ahadi (Light of One), coming out of His self-isolated oneness, intended to manifest Himself in multiplicity. These stages are also termed as “Tanzalat-e-Satta. Many saints have explained these Tanzalat-e-Satta in their books. Abu Saeed Mubarak Makhzoomi has discussed them in his Arabic book called Tohfa Mursala. They are also discussed in the exegesis of Fusoos-ul-Hikam, a book by Ibn Arabi. Alam-i-HaHoot (Realm of He-ness): The level of HaHoot refers to HaHooiyat (The Unknowable and Incomparable world). It is an Arabic term which pertains to the Divine's Essence prior to manifestation. The spiritual stage related to it is called Ahdiyat (Alonehood). This is the Realm of pre-existence and a level of non creation. According to sufis, this state of Ahdiyat is incapable of being conceived, incapable of interpretation and is beyond all logical bounds. At this stage Allah is all alone and hidden in his own veil and cannot be exemplified with anything. Nothing exists here, neither the universe nor the creation. Here the Zaat (Divine essence) and neither His attributes are revealed or manifested. Alam-i-Yahoot (Realm of First Manifestation): The spiritual stage pertaining to YaHoot is referred to as Wahdat (Oneness). YaHoot is the first level of manifestation of "Hoo". When the Divine Essence desired to manifest, He manifested Himself in the form of Noor-e-Mohammad (Light of Muhammad). Since YaHoot is a world of Oneness, so it clarifies that Noor of Mohammad is a manifestation of God's Essence and is not a separate entity. This is the first step towards Divine descent. The creation has not started yet. Here Hoo is called Allah which in Arabic means "the worshippable one", because there is a being in the form of Noor of Mohammad who worships Allah. And the level is called yaHoot because there is an entity who would address Hoo as YaHoo (O’Hoo). Alam-i-LaHoot
