—“Our Lord, You have encompassed all things in mercy and knowledge” (Ghāfir 40:7)—and He is al-Quddūs (the Most Holy), al-Salām (the Source of Peace), exalted and sanctified far above every flaw, defect, or deficiency, above all resemblance to His creation, and above having any rival among them.
The same applies to the rest of the Most Beautiful Names: consider them in light of this noble principle and a vast gateway to knowing Allah will open before you. Indeed, the very foundation of knowing Him is to understand—as much as each servant is able—the magnificent meanings contained in His Names and what they entail. Yet no created being can fully grasp that knowledge, nor can anyone enumerate His praise; He is as He has praised Himself, and far beyond what His servants can say in His praise.
An example of this rule is His statement: “Cooperate in righteousness and piety, but do not cooperate in sin and aggression” (al-Māʾidah 5:2). “Righteousness” covers every form of virtue and goodness, and “piety” embraces everything that must be avoided—every danger, sin, and prohibition.
“Sin” is an inclusive term for anything that incurs blame and leads to disobedience, while “aggression” is likewise comprehensive, spanning every transgression against people—whether against their lives, their property, or their honour—as well as wrongdoing against the community at large, against governing authorities, and against the very limits set by Allah.
In the Qur’an the word maʿrūf (that which is universally recognised as good) is an all-embracing term for everything whose goodness is affirmed by revelation and sound reason; its opposites are munkar (reprehensible), evil, and obscenity.
The Prophet—peace and blessings be upon him—drew his nation’s attention to this principle and urged them to observe it when he taught them, in the tashahhud of prayer, to say: “Peace be upon us and upon the righteous servants of Allah.” He explained, “When you say that, the greeting reaches every righteous servant in the heavens and on earth.” (Reported by al-Bukhārī.)
Examples of this principle in the Qur’an are exceedingly numerous.
