No need to thank me brother Sardar
, if this helps, about the term "ghaib" The unseen / unknown
The word "unseen" means anything which us humans cant see and cant know, be it from the past or from the future. For example, when Allah in the Quran tells us a story about a past nation or prophet, in the end He often says something like "These We reveal to you from the unseen, you had no knowledge of them before". Or, when talking about the Hour and its time, its a future event and noone knows it except God, and God never revealed it to any of His prophets, or other creatures, because that forms part of the "unseen". Now, knowing something from the unseen, and knowing the unseen, its not the same thing. Prophets knew something from it (from the unseen) only when Allah revealed it to them, often as a sign of prophethood for their people. But none of people or angels or jinns knew or knows the unseen as a whole, it belongs to Allah only.
And by the way, please make sure the translations you use is trustful
