Musannaf Ibn Abi Shaybah 153 — How the head is wiped

Sayyidah al-Rubayyi' (may Allah be pleased with her) said: The Prophet (peace and blessings be upon him) used to visit us often. Once he came, and we placed water for ablution for him. He performed ablution and wiped his head in this way: he began from the back of his head, and then brought his hands forward to his forehead.
