A woman should not mourn for any dead person more than three days except her husband for whom she should mourn four months and ten days. She should not wear dyed clothes (while in mourning) except ‘Asb (an unattractive Yemeni garment), nor should she apply kohl or touch perfume, except when she becomes purified (after her menses), as she may then apply a little Qust or Azhfār (types of incense). [Al-Bukhari]

"«لا تُحِدُّ امرأة على الميت فوق ثلاث، إلا على زوج: أربعة أشهر وعشرًا، ولا تلبس ثوبًا مَصْبُوغا إلا ثوب عَصْبٍ، ولا تكتحل، ولا تَمَسُّ طيبًا إلا إذا طهرت: نبُذة من قُسط أو أظْفَار». [صحيح.] - [متفق عليه.]"
