Yazid bin Aws narrated: When Abu Musa (may Allah be pleased with him) fell ill, his wife began to weep over him. He said to her: Have you not heard what the Messenger of Allah (peace and blessings be upon him) said? She replied: Of course. Then when he passed away, Yazid said: I met that honorable lady and asked her: What did Abu Musa say to you? Did you not hear what the Messenger of Allah (peace and blessings be upon him) said? She replied: Of course. Then she said: The Messenger of Allah (peace and blessings be upon him) said: "Whoever wails (in mourning), shaves her head, or tears her clothes is not from among us."
