“Allah (swt) is Self-sufficient (Samad) (even though everything is in need of him in every aspect, he is the one who is not in need of anything.)” (Ikhlas, 2)Allah does never need anything that he could need our worship! It is us who needs worship. If a merciful doctor insists on his patient to use the medicines on healing his pain, then if the patient should tell that doctor: “Do you need my using these medicines that you insist that much?” That statement of the patient shows how ignorant and illogical the patient is.
Human Beings Need Worship ('ibadah); Because Their Impotence and Poorness Make Them Dependent on Being Under the Maintenance of An Existence That is Fully Omnipotent, Eternal and Self-Sufficient.
