You mentioned that "cologne" is among intoxicating substances

The questioner : The questioner brother says: You mentioned, O honorable Shaykh, that cologne is considered khamr (intoxicants) because it contains alcohol, which is the cause of its intoxication. Does this also apply to many substances that are originally intoxicating if used for a purpose other than what they were made for, such as gasoline and many markets, or in some ingredients that contain alcoholic substances in their manufacture, such as vanilla used in making sweets? And is the curse in the hadith if the purchase is for the purpose of intoxication, or is the curse for everyone who deals in it, even for purposes other than intoxication?

The Shaykh : There is also a recording with a simplified answer to this question; therefore, to save time, we will not lengthen the answer, but rather we will take from it what indicates the summary of the speech there.
Alcohol, we said: Alcohol is an intoxicant, and it is the basis for khamr being an intoxicant, so it is not permissible to sell or buy it absolutely, for any intention. This is detailed there, and we cited during the detail the hadith of Abu Talhah al-Ansari who had a skin of khamr for his orphans, so when its prohibition was revealed, he came to the Prophet (peace and blessings be upon him) and said to him: Should I turn it into vinegar? He said: . He did not allow him to convert it into vinegar such that in the vinegar-making there is a radical change to the chemistry of the khamr, and in that there is a benefit for these orphans; he said: ; so there is no way, ever, in Islam to permit the making of khamr, especially the making of the mother of the mother of khamr, which is alcohol, or selling it or buying it or carrying it or the like, due to the arrival of authentic hadiths prohibiting that, rather cursing its doer, knowing that this hadith stems from a Quranic rule: .
Therefore, if there is a type of alcohol that is not intoxicating, and this is what I do not know; then naturally it takes another ruling. And if there are other substances, as the questioner gave the example of gasoline, and this is a discussion that took place between me and one of our brothers on the road; I said: My brother, I do not know that gasoline intoxicates, but it may narcotize, and I know from my personal experience that many people do not distinguish between the intoxicating substance and the narcotic substance. The intoxicating substance is khamr, whose origin is alcohol, whereas the narcotic substance has another ruling in Islam. It is sufficient in the difference between the two substances that khamr is forbidden, whether little or much; what intoxicates from it and what does not, as came in the authentic hadiths.
Then, whoever drinks khamr, the hadd of flogging is established against him, at least forty lashes. As for the one who uses narcotics like hashish and opium and the like; this does not have a specified hadd in Islam, rather the hadd returns to the opinion of the Muslim rulers; and this falls under the category of ta'zir (discretionary punishment). So with that, the narcotic differs from khamr in that khamr is not permissible to use for treatment; because the Messenger (peace be upon him) said: . As for the narcotic, it is permissible to use it in a small amount when there is a need, let alone when there is a dire necessity.
Yes.
So gasoline, excuse me, the gasoline I know is that it narcotizes. We feel when we ride in a car and the car is a bit old, and the device called the "carburetor" – I don't know what this foreign name is – it starts to leak, filtering gasoline to the outside, so the smell of gasoline enters the passenger, and he is almost fainting, meaning because of the heaviness of this smell. So the gasoline I know is that it is a narcotic. But if it is established by some of our chemical brothers... a precise test on gasoline, and it is established with them that it is intoxicating, much like khamr; this is information we add to our previous information, and we include gasoline in the group of forbidden khamr.

The questioner : The cars stop.

The Shaykh: Yes.

The questioner : Then the cars stop!!
