Sheikh Salman al-Oadah
It is lawful to buy, sell, and use perfumes that contain alcohol, because the alcohol is mixed with other materials.
It is not used as a drink, otherwise would be unlawful, even for selling and buying.
If we wish to argue that alcohol is impure then we have to say the same about many items such as gasoline and other petroleum products.
Even for intoxicants, the preferable saying is that it is pure in and of itself. When the Qur’ân calls it as abomination, the meaning goes to that it is bad and forbidden and that is why it is mentioned as an abomination along with gambling, sacrificing to idols, and divination by arrows, none of which are physical impurities according to the agreement of the scholars. Therefore, there is no evidence in this verse that it is impure.
If intoxicants were impure, they would not have been poured into the streets of Madinah while there is severe warning for who those who urinate in the roadways. Also, when intoxicants were prohibited, people were not requested to wash their utensils or clothes from it. Even the people who held the containers of liquor were not required to wash. In one hadîth, the Prophet (peace be upon him) did not even order the containers to be cleaned. [Sahîh Muslim (1579) and Sunan al-Nasâ’î (4664)]
All this is further supported by the general principle in Islamic Law that things are to be deemed pure unless there is evidence to indicate otherwise.
