“Lord of the heavens and the earth and all that lies between them. So worship Him and patiently persevere in His worship. Do you know of anyone equal to Him?”
He then establishes His all-encompassing knowledge and freedom from forgetfulness on the grounds that He is the “Lord of the heavens and the earth.” His lordship over the heavens and the earth—and the fact that they exist according to the finest and most perfect order, with no negligence or neglect, aimlessness or futility—is decisive proof of His all-encompassing knowledge. Therefore, do not preoccupy yourself with that. Rather, devote yourself to what benefits you and brings you good: worshipping Him alone, without partner. “And patiently persevere in His worship”—that is, make yourself remain steadfast in it, strive against your lower self, uphold it fully, and perfect it to the best of your ability. Devoting oneself to the worship of Allah also provides the worshipper with solace from every attachment and desire. As Allah Most High says: “Do not let your eyes extend toward what We have given various groups of them to enjoy—the splendor of the life of this world—so that We may test them through it,” until He says: “Command your family to pray and patiently persevere in it,” to the end of the verse.
“Do you know of anyone equal to Him?” That is, do you know of any created being who is His peer, likeness, or equal? This is a rhetorical question intended as a negation—a truth established by reason. In other words, you know of no peer or likeness to Him, for He is the Lord, while all besides Him are under His lordship; He is the Creator, while all besides Him are created; He is self-sufficient in every respect, while all besides Him are intrinsically needy in every respect; and He is the Perfect One, possessing absolute perfection in every respect, while all besides Him are deficient and possess no perfection except what Allah Most High has granted them. This is decisive proof that Allah alone deserves to be worshipped, that worshipping Him is truth, and that worshipping anything besides Him is falsehood. For this reason, He commanded that He alone be worshipped and that one patiently persevere in worshipping Him, grounding this command in His perfection and His exclusive possession of grandeur and the most beautiful names.
