I say, and with God's success: The water of ritual impurity: it is the water used to remove the ritual impurity, or the water used with the intention of drawing closer to God: the water becomes used by one of two matters: either by removing the ritual impurity, whether with intention or without intention, or with the intention of drawing closer to God even if one is not in a state of ritual impurity. Its ruling is that it is pure but does not purify from ritual impurity, so it is permissible to remove actual impurity from clothing and the body with it, but it is not permissible to perform ablution or bathing with it. The water becomes used as soon as it separates from the body according to the correct opinion; because the ruling of usage falls before separation due to the necessity of purification — that is, if we consider it used before separation, it would not be permissible to purify with it — and there is no necessity after separation. Refer to: Sharh al-Wiqayah p. 99, al-Hidayah 1: 20, Nur al-Iidah p. 23, and al-Sayah 1: 396-397, and God knows best.
