And if a man(1) were to say, “By Allah, I will certainly do what Allah has made obligatory upon me, or what [Allah] loves for me,(2) if Allah wills,” but then failed to do so, he would not have broken his oath, by agreement among the jurists.
But if he were to say, “By Allah, I will certainly do what Allah has made(3) obligatory upon me, if Allah loves and approves of it,” he would have broken his oath if(4) he failed to do so, without any disagreement known to us(5).
Accordingly, the invalidity of the argument advanced by those who deny divine decree has become clear. If one of them says, “Every rational person regards anyone who commands what he does not will and forbids what he wills as foolish,” he should be asked: “If someone commands another person to do something but does(6) not intend to do it on his behalf, is he foolish(7) or not?”
It is well known, by agreement among all rational people, that anyone who commands another person to do something without intending to perform that act himself(8) or assist him in doing it is not foolish. Indeed, all the commands issued by wise and rational people(9) fall into this category.
When a physician directs a patient to take medicine, he is not obliged to help him take it. When a mufti instructs a questioner to fulfill an obligation incumbent upon him, the mufti is not obliged to help him fulfill it. And when an adviser counsels someone seeking advice to engage in commerce, farming, [or marriage](10), the adviser is not obliged to do that himself(11).
