for omitting them because of his independent juristic reasoning, his following another scholar, or his excusable ignorance, is all the more fitting and appropriate. Just as Islam wipes away what came before it, repentance wipes away what came before it—especially the repentance of someone who had a valid excuse and then received or understood the text, having previously been unable to hear and understand it. This is abundantly clear. The same applies to contracts he concluded and assets he received without knowing that they were prohibited, owing to excusable ignorance or an interpretation. According to one of the two views, the same ruling applies to him in these matters, with even greater justification.
Thus, if someone enters into a transaction that he believes permissible on the basis of an interpretation—whether involving usury, gambling, the price of wine, an invalid marriage, or something else—and then the truth becomes clear to him and he repents, or he brings his case before us for judgment, or seeks a legal ruling from us, he is allowed to retain what he has received under these contracts. His marriage is also allowed to stand if its invalidating circumstance has ceased to exist. For example, he may have married without a guardian or without witnesses, believing this permissible; married a fifth wife during the fourth wife’s waiting period; entered into a disputed form of marriage intended to make a woman lawful again for her former husband; or done something similar. Even if he subsequently discovers that the marriage was invalid, it is allowed to stand.
If, however, he married on the basis of independent juristic reasoning and subsequently concluded, through independent juristic reasoning, that the marriage was invalid, this rests on the principle that one juristic judgment is not overturned by another, whether in adjudication or in issuing legal opinions. That is a separate basis for the ruling. Our point here, however, concerns the case in which he becomes certain of the prohibition through a definitive text, with a certainty like that of
