[Trading in Intoxicants and Usurped Wealth]

Answer to the first question: Whatever was realized from trading in wine is unlawful—filthy gain—and it is not permissible to consume it, as is related in the well-known report from the Prophet—May Allah bless him and his family and grant them peace. It also came from the Prophet—May Allah bless him and his family and grant them peace: “Indeed Allah, when He forbids a thing, forbids its price [as well],” or as he said. Apparently, this is a matter of agreement among all the scholars.
I do not think that distinguishing here between a specified price and an unspecified one avails anything. The truth is that whatever was obtained by means of trading in wine—selling it and buying it—is unlawful, whether the price was specified or not, due to the apparent generality of the evidences.
As for the wealth he acquired through that trade, some have said that it should be spent in public interests—such as [supporting] scholars and students. This view is more cautious in religion and closer to safety.
It may also be said: If a person repents from that, ceases it, and returns to Allah, then what is in his hand becomes lawful to him.
One may infer this from Allah’s saying in the verse on usury: “So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah.” [Al-Baqarah:275], and His saying: “And do not compel your slave girls to prostitution, if they desire chastity, to seek [thereby] the temporary interests of worldly life. And if anyone should compel them—then indeed Allah is to them, after their compulsion, Forgiving and Merciful.” [An-Nūr:33], and His saying regarding the highway robber: “Except for those who return [repenting] before you apprehend them—then know that Allah is Forgiving, Merciful.” [Al- Mā’idah:34].

As for the answer to the second question: The usurper must return the like of what he usurped or its value and seek pardon; as for the profits, their ruling follows what has preceded.
