Benefits of the Hadith (The Messenger of Allah (peace and blessings be upon him) was asked about wine being made into vinegar . . .).

The Shaykh : Among the benefits of this hadith is the prohibition of intoxicants, because the prohibition of making them into vinegar indicates their prohibition a fortiori. This is a matter of consensus based on the evidence of the Book and the Sunnah. The Muslims have agreed on the prohibition of intoxicants. The scholars said that one who denies the prohibition of intoxicants, having lived in the lands of the Muslims, is a disbeliever and an apostate who must be given the opportunity to repent. If he repents and acknowledges the prohibition, that is well; otherwise, he must be killed as an apostate.
And among the benefits of this hadith is blocking the means to harm. How so? The Prophet (peace and blessings be upon him) prohibited making intoxicants into vinegar so that one would not keep them, for perhaps his soul might prompt him to drink them.
Now, among the benefits of this hadith is that the word of response serves the place of the sentence, as in his saying: This is a consistent rule, even in contracts. If a man is asked, "Did you accept the sale?" and he says, "Yes," the sale is valid. If a woman's guardian says, "I have married you to my daughter," and the husband is asked, "Did you accept?" and he says, "Yes," it suffices and the marriage contract is valid. If he is asked, "Did you divorce your wife?" and he says, "Yes," she is divorced.
