Usayd ibn Abu Usayd At-Tābi'i reported that one of the women who gave the pledge to the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Among the matters in respect of which we gave the Messenger of Allah (may Allah's peace and blessings be upon him) the pledge not to disobey him in any goodness was that we should not scratch our faces, bewail, tear our clothes up, or dishevel our hair (in grief)."
