Umm Atiya reported,

The Messenger of Allah ﷺ said, "A woman must not mourn for any deceased person more than three days, except for her husband, for whom she mourns four months and ten days. During this period she must not wear a dyed garment, except one made of asb fabric, nor apply kohl, nor touch perfume, except that when she becomes pure from her menses she may use a small portion of qust or azfar."

Muslim 3740
