Musnad Ahmad 788:132

'Affan narrated to us, Shu'bah narrated to us, from Mansur, from Ibrahim, from Yazid ibn Aws, who said: Abu Musa fainted, so they wept over him. He said: "I am free of whomsoever the Messenger of Allah (peace and blessings of Allah be upon him) was free of." They asked his wife about that: "What did the Messenger of Allah (peace and blessings of Allah be upon him) say?" She said: "Do you not know what the Messenger of Allah (peace and blessings of Allah be upon him) said?" They mentioned that to his wife, and she said: "Of those who shave (their heads in grief), and those who raise their voices (in wailing), and those who tear (their garments)."
