Explanation of the author's statement: "And the removal of impurity"

The Shaykh : Pay attention to his saying "and the removal of impurity", and not "and the elimination of impurity." The removal of impurity is purity, whether it goes away by itself or is removed by another means; in either case, it is considered purity. Impurity is ritual impurity (najasah). They defined ritual impurity as any substance whose consumption is forbidden, not because of its harm, nor because it is disgusting, nor because it is intrinsically forbidden. So, when we say "whose consumption is forbidden," this excludes what is permissible, for anything permissible to consume is pure. When we say "not because of its harm," this excludes poison and the like, for it is forbidden, but why? Because of its harm. When we say "nor because it is disgusting," this excludes phlegm and the like. When we say "nor because it is intrinsically forbidden," this excludes hunting while in the state of ihram and hunting inside the Haram within the miles, for its consumption is forbidden, but because of its intrinsic prohibition. In any case, ritual impurity will come to us, if Allah wills, in its chapter and its explanation. The original ruling for things is purity, as will also come later. And regarding the author's saying "and the removal of impurity", I said that it is more comprehensive than "and the elimination of impurity." It is more comprehensive because impurity may go away by itself. For example, if we assume that a ground became impure with urine, and then rain came and purified it, it becomes pure. Was there an elimination? No, but the impurity went away. Or if I have water that became impure by change, its smell changed, and then the smell went away by itself, it becomes pure. Was there an elimination? No, it did not become pure [by elimination]. Or if a person has wine and it ferments by itself, it becomes pure, even though the correct view is that wine is pure even if it remains in its state as wine, as will come later, if Allah wills. Now, this is the definition of purity in technical terms: it is the removal of the state of ritual impurity (hadath) and what is in its meaning, and the removal of impurity. The author began with purity for two reasons. The first reason is that purity is a cleansing, a cleansing from harm. They say that cleansing comes before beautification, meaning: purify the thing from what defiles it of defects, then complete it with perfections. Beautification is second. The second reason is that purity is the key to prayer, and prayer is the most emphasized pillar of Islam after the testimonies of faith. Therefore, the jurists, may Allah have mercy on them, began with the Book of Purity because it is the key to prayer. In any case, purity requires something with which to purify, with which to remove the state of ritual impurity, to lift the state of ritual impurity, and to remove the impure substance, and that is water. For this reason, the author began with it.
