to go beyond what the texts have stated. Had the Messenger, peace and blessings be upon him, not said that his father is in Hell, the implication of the legal principle would have been that he would not be punished and that his case would be left to Allah, like the rest of the people of the interval. The preponderant view is that the people of the interval will be tested on the Day of Resurrection in whatever manner Allah wills. As for these people, they believe themselves to be upon Islam, and no one has come to teach them. Indeed, they may even have misguided scholars among them who tell them that what they are upon is the truth.
Therefore, the one who denies that zakat is obligatory must be aware of the ruling. If he denies it while knowing the ruling, he becomes a disbeliever. If he is ignorant, but we teach him and explain the textual proofs to him, and he persists in his position, then he becomes a disbeliever, because he is aware of the ruling.
From this, it becomes clear that acknowledging the ruling is not a condition. Once the ruling has reached a person in a clear and manifest manner, the proof has been established against him, whether he acknowledges it or denies it. Even if he denies it, that does not benefit him or remove the ruling from him. Otherwise, Pharaoh—who denied the message of Moses, peace be upon him, despite acknowledging it inwardly—would have been a believing man who was in the right. But he was not. The condition is that the proof reach a person in a manner that makes the matter clear to him. Once it has reached him, his acknowledgment of it is not a condition; he is judged to be a disbeliever even if he does not acknowledge it.
If we inform him and he persists in claiming that it is not obligatory, yet pays it as voluntary charity, he becomes a disbeliever. Accordingly, the author’s statement, “Whoever withholds it while denying that it is obligatory,” is not a qualifying restriction in the ruling, because the determining factor is denial. Thus, if he denies its obligation while knowing the ruling, he becomes a disbeliever, whether he pays it or does not pay it.
