Explanation of the Author's Statement: "The Chapter on Istinja'"

The Shaykh : Then the author (may Allah have mercy on him) said: "The Chapter on Istinja'". In this chapter, the author mentions istinja' and the etiquettes of relieving oneself. Istinja' is a verbal noun derived from the root *naja*, which in the language means to cut. It is said, "I cut the tree," meaning I severed it. Istinja' is the removal of what exits from the two passages using water or stones, and in doing so, this impurity is severed. This is how the derivation relates to the technical meaning. Linguistically, it is from *naja*, which is cutting. As for the technical definition, it is the removal of what exits from a passage using water, or the removal of its ruling based on the opinion that wiping with stones does not purify, or the removal of its ruling using stones or the like. You have understood that it is the removal of what exits from a passage using water, or the removal of its ruling using stones or the like. However, the correct statement is that it is the removal of what exits from a passage using water, stones, or the like, because the correct view is that wiping with stones purifies completely, just as water does.
