Sunan an-Nasa'i 1865

Muhammad ibn al-Muthanna narrated to us: Muhammad narrated to us: Shu‘bah narrated to us, from Mansur, from Ibrahim, from Yazid ibn Aws, from Abu Musa, who lost consciousness, and one of his umm walad [a woman who had borne him a child] wept. When he regained consciousness, he asked her: ‘Have you not heard what the Messenger of Allah said?’ We asked her, and she said: He said: ‘He is not one of us who wails loudly, shaves his head, or tears his garments.’
