It is cleanliness and integrity, and its opposite is impurity, and purification is the pure purifier; That is, the one who purifies himself with it, and the pure water, which is the water that purifies him with, and for example: the water that comes down from the sky, as God Almighty said: (And We sent down pure water from the sky), as well as sea water; Where the Messenger of God, may God’s prayers and peace be upon him, said: (Its water is purified, its dead meat is permissible), [2], and Sibawayh said: (pure water is water that removes impurity, and removes impurity), and scholars have defined purity idiomatically with many definitions, and based on that it can be said ; Purification is the removal of impurity and the removal of impurity, as the major and minor impurity is removed by ablution and washing, or the delivery of a disinfectant to a place that must be purified, and the disinfectant is water when it is present or level when it is not, as the Almighty said in Surat Al-Ma’idah after mentioning the purification of the major and minor impurity: (what God wants to place hardship upon you, but He wants to purify you and to complete His favor upon you that you may be grateful). He purifies himself with the impurity, as the Messenger of God, may God’s prayers and peace be upon him, said: (God does not accept the prayer of any of you if he has impurity until he performs ablution), and as for removing impurity, it is by removing it from the place And an example of that is purifying the vessel, as the Messenger of God, may God’s prayers and peace be upon him, said: (The purification of one of you’s vessel if a dog licks it is to wash it seven times, the first of them with dirt).
