Musannaf Ibn Abi Shaybah 84 — Running water between the fingers

It is narrated from Sayyiduna Laqit bin Sabirah (may Allah be pleased with him) that he said: I said: O Messenger of Allah! Tell me the method of ablution. He (peace and blessings be upon him) said: "Perform ablution thoroughly, pass your fingers between the fingers (khilal), and draw water deeply into the nose unless you are fasting."
