It is narrated from Sayyidah Umm Atiyyah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "A woman should not mourn for more than three days for anyone except her husband; for her husband she mourns four months and ten days. She should not wear dyed clothing except a washed garment, nor apply kohl, nor use henna, nor touch perfume, except that when becoming pure after her menstruation she may use qust or azfar (a light fragrance)."
