Musannaf Ibn Abi Shaybah 138 — How many times the head is wiped

Yazid bin Abi Ziyad said: I went to Abd al-Rahman bin Abi Layla. He called for water for ablution and performed ablution. He wiped his head once and washed his feet three times each, and said: "This is how I saw Sayyiduna Ali (may Allah be pleased with him) perform ablution."
