Wilayah is from “Wila” which means understanding, In Islamic terms it is used to understand the Reality of Islam and the Universe.
Allah almighty sends his 1lac and 24 thousand messengers to the earth for advice the people. They advise the people to the way of Allah almighty’ called Islam, from Hazrat Adam a.s to Hazrat Muhammad s.a.w.a all prophets have one message and that was the message of islam, they have different “sharah” for different times but all are at one aim which is called Islam. Prophet Muhammad s.a.w.a is the last prophet of Allah and he is not for a caste, Nation or community but for Human being and the whole universe, so his “Sharah” is final for all over the universe including all messengers from Hazrat Adam a.s to Hazrat Esa a.s (Jesses). All Messengers are also the followers of Muhammad s.a.w.a
It is a great reality that every messenger told about Muhammad s.a.w.a coming to their nations. In Arabic language “AALAM” means Universe, there are 18000 universes created and destroyed by Allah Almighty and finally Allah creates our universe “THE UNIVERSE OF HUMAN BIENG” Allah make Adam a.s with his hands from different types of soil i.e. eyes of Adam a.s were made by the soil of Hoz-e-Kosar (a hoz of paradise) but Allah Almighty create the Noor-e-Muhammadi first of all, when no one is created by him’ he create Noor-e-Muhammadi when there was no universe at all.
Allah makes Paradise and decorated as his best for his beloved Muhammad s.a.w.a now he decide to create Adam a.s so he made Adam and when his statue is able to maintain body he ordered him with “ROOH” to alive. Allah placed Adam a.s in paradise under Muhammad s.a.w.a, Ali a.s, Fatima, Hassan a.s and Hussein a.s. they teaches him the names of things “Allah gives Adam the knowledge of Names” so they teaches him there names and to speak. After visit Allah placed him in his paradise and strictly ordered that he never go towards a tree.
Adam a.s is alone now in his paradise and feels boring so Allah give him Hawa s.a as a gift to get there time best.
