Musannaf Ibn Abi Shaybah 25006 — Hanging amulets and ruqyah

It is narrated from Yazid, who said: Zayd bin Wahb informed me that Sayyiduna Hudhayfah (may Allah be pleased with him) went to visit a sick man of the tribe of al-Nakha'. He set out and I set out with him. He entered upon him and I entered with him. Then Sayyiduna Hudhayfah (may Allah be pleased with him) touched his upper arm and saw a thread on it. He took hold of the thread and broke it. Then he said: Had you died while this thread was on your arm, I would not have prayed the funeral prayer over you.
