Advice of Scholars - ALLAHU TA’ÂLÂ IS WÂJIB-UL-WUJÛD
Hadrat Imâm-i Rabbânî says in the 17th letter of the third volume of his Maktûbât:
Allahu ta’âlâ exists by His zât; His existence is of Himself. As He exists now, He has always been existing and will continue to exist. There cannot be nonexistence before or after His being. His existence is indispensable. That is, He is Wâjib-ul-wujûd (the Indispensable Being). There cannot be nonexistence at that rank. Allahu ta’âlâ is One. That is, He does not have a partner or a likeness.
He does not have a partner in being Wâjib-ul-wujûd, in being worshipped or in being worthy of worship. For having a partner, Allahu ta’âlâ has to be insufficient, dependent, which are defects and faults. There cannot be deficencies in wujûb, and ulûhiyyat. He is sufficient, independent. That is, He is by Himself. Then, there is no need for a partner or a likeness. And being unnecessary is a defect and is not compatible with wujûb and ulûhiyyat. As it can be seen, to think that He has a partner shows that each of the partners is insufficient. That is, to think that there is a partner exposes the fact that there cannot be a partner. That means to say that Allahu ta’âlâ does not have a partner. He is one.
