I say, and with God's success: Washing (al-ghasl) is the pouring of a liquid - water - onto the place, and in ablution (wudu), it refers to the face, hands, and feet. Wiping (al-mas'h) is the touching, and it is for the head. Therefore, if one washes the parts of his ablution but does not pour the water, as when he uses it like oil, it is not permissible according to the apparent narration. Likewise, if he performed ablution with snow and nothing dripped from it, it is not permissible. However, if two or three drops dripped, it is permissible due to the presence of pouring. Refer to: Al-Ikhtiyar 1: 12, Al-Bada'i 1: 3, Hashiyat 'Issam al-Din Q6/A, and Fath Bab al-'Inayah 1: 41, and God knows best.
