The poet said (1):
“I gave you a firm command, yet you disobeyed me.”
The very purpose for which the messengers were sent is that the Sender be obeyed, and that cannot be achieved except by carrying out His commands. Refraining from what He has forbidden is simply a completion and corollary of fulfilling those commands. Hence, if someone were to avoid the prohibitions yet fail to do what he has been ordered, he would not be regarded as obedient but as disobedient. By contrast, if he performs the prescribed duties while also committing the prohibitions, then although he is certainly sinful on account of the latter, he remains obedient for fulfilling the former. As for the one who neglects the command altogether, he cannot be deemed obedient merely because he keeps away from the prohibitions.
Tenth point: Complying with the command is servitude, a means of drawing near to Allah, and an act of service; it is the very worship for which the creation was brought into being, as He, exalted is He, says, “I did not create jinn and mankind except to worship Me” (Al-Dhāriyāt 51:56). He thus informs us that He created them solely for worship, and likewise sent to them His messengers and revealed His scriptures so that they might worship Him. Worship, then, is the end for which they were created; they were not created merely to refrain from acts, for such sheer abstention is a non-entity that contains no perfection in itself, whereas fulfilling the commanded duties is a positive reality that is sought in its own right.
This becomes clearer in the eleventh point: what the prohibition seeks is the non-occurrence of the act—pure absence—whereas what the command seeks is the actual performance of an act—a concrete existence. The object of the command is bringing something into being, while the object of the prohibition is non-existence, which contains no perfection unless it is accompanied by some positive reality. For non-being, considered purely as such, carries neither excellence nor benefit unless it is tied to an actual, positive good, and that—
