Al-Ghaib is an Arabic expression used to convey that something is concealed (unseen). It is an important concept in Islam, encompassing not only the realm of the divine, including angels, paradise, and hell, but also future events, which only God knows. Jinn (daemons), who are also generally invisible but bound to earthly lives, are thought be restricted from the unseen as humans are. In the Quran it has 6 forms and 3 meanings. But it can also be used in a general sense to refer to something that is known to some but concealed from others. Meaning In Arabic, al-Ghaib refers to anything that is hidden in some manner. The term is composed of two words (a definitive article and an adjective), "al" and "Ghaib", literally translating to "the" and "unseen" respectively. It possesses multiple intricate meanings stemming out from the figurative translation "the depth of the well."

(12:52) The Unknown or Hidden – "[Allah is] Knower of the unseen and the witnessed, the Grand, the Exalted." (13:9) The Future – "Say, "I hold not for myself [the power of] benefit or harm, except what Allah has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe."
