It was narrated that Safwan bin Muhriz said: “Abu Musa fell Unconscious and they wept for him. He said: ‘I say to you the words of disavowal that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: He is not one of us who shaves his head (as a sign of mourning), rends his garments, or raises his voice in lamentation.”(Sahih)
