Explanation of the author's statement: "And the impure manure and the impure oils, and not the ritually defiled ones"

The Shaykh : Then the author said "And the impure manure" Is this the beginning of the lesson? That is to say, it is not permissible to sell impure manure. Manure is what is known as fertilizer used for trees and crops. This fertilizer is divided into two categories, or rather three: impure fertilizer, pure fertilizer, and ritually defiled fertilizer. It is not permissible to sell impure fertilizer, such as donkey dung, human excrement, and the like. The reason for this is that it is not permissible to use this type of fertilizer. Pay attention, did you understand what manure is? It is the fertilizer used for crops and trees. It is not permissible to sell the impure kind, such as donkey dung or human excrement. Why? Because it is not permissible to use it as fertilizer. That means if a person fertilizes with something impure, it would be forbidden. However, most scholars permit fertilizing with impure substances, allowing trees and crops to be fertilized with donkey dung and human excrement. So, based on this opinion, do we say it is permissible to sell it because it is beneficial? It appears that it is not permissible, even though it is beneficial. Why? Because when the Prophet (peace and blessings be upon him) said meaning they make lamps from it, he said meaning the sale, even though there is benefit in it. But the Prophet (peace and blessings be upon him) prohibited its sale because it is impure. Therefore, we say that impure manure is not permissible to sell, even if we say it is permissible to use it as fertilizer. Did you understand?
The second type of fertilizer is the ritually defiled one, or one of the categories of ritually defiled fertilizer. Is it permissible to sell it? The answer is yes, it is permissible to sell it because it can be purified. An example of ritually defiled fertilizer is soil upon which an animal from those whose urine is impure has urinated. This soil is originally pure, but impurity has come upon it, so what is it? It is ritually defiled. Is it permissible to sell this ritually defiled soil before we purify it?

The questioner : Yes.

The Shaykh : It is permissible because its impurity can be removed. It is like if a person sells a ritually defiled garment. If a person has a ritually defiled garment and sells it to someone, the sale is permissible, but he must inform the buyer that it is ritually defiled so that he is not deceived. So, the sale of impure manure is forbidden, the sale of ritually defiled manure is lawful, and the sale of pure manure is permissible? Yes, its sale is lawful, a fortiori. Yes.
He says "And the impure manure, and not the impure oils, and not the ritually defiled ones" It is not permissible to sell ritually defiled oils. The evidence for this is the saying of the Prophet (peace and blessings be upon him) So they said "What about the fat of carrion? It is used to tar ships, to grease skins, and people use it for light." He said meaning their sale, even though they mentioned that people benefit from it. So, it is not permissible to sell impure oils. Is it permissible to benefit from them? The answer is yes, it is permissible to benefit from them in a way that does not involve direct contact, such as greasing skins, tarring ships, and using them for light. Now, "And not the ritually defiled ones" means it is not permissible to sell ritually defiled oils. An example of impure oils is oils made from the fat of carrion. These are impure oils because carrion is impure, and the oils extracted from its fat are impure. Ritually defiled oils are pure oils upon which impurity has come, such as a person who has a gallon of oil, let us say, and impurity falls into it. Is it permissible to sell it or not? It is permissible. Why? We say it is permissible according to the stronger opinion, but the school of thought says it is not permissible. It is not permissible to sell ritually defiled oils. Why? They said because it cannot be purified, and if it cannot be purified, it becomes like impure substances. The correct view is that selling ritually defiled oils is permissible because they can be purified, so it is like selling a ritually defiled garment.
So, the author's statement in his saying "The impure oils" that it is not permissible to sell them is correct. What is the evidence?

The questioner : ... .

The Shaykh : The hadith The hadith of Jabir. Regarding ritually defiled oils, the author says it is not permissible to sell them, but the correct view is that selling them is permissible because the prohibition of their sale is based on the assumption that they cannot be purified. However, the correct view is that their purification is possible. But how can they be purified if they are oils? It is possible by adding substances to them that purify them, or by adding water to them and boiling them. The point is that whenever their purification is possible, it is permissible to sell them.
The author (may Allah have mercy on him) said "And the impure oils" You have "and not the ritually defiled ones" here. Is this a mistake? "And not the ritually defiled ones."
