قالت زينب وسمعت أم سلمة، تقول جاءت امرأة إلى رسول الله صلى الله عليه وسلم فقالت يا رسول الله إن ابنتي توفي عنها زوجها وقد اشتكت عينها أفتكحلها فقال رسول الله صلى الله عليه وسلم ‏"‏ لا ‏"‏‏.‏ مرتين أو ثلاثا كل ذلك يقول لا، ثم قال رسول الله صلى الله عليه وسلم ‏"‏ إنما هي أربعة أشهر وعشر، وقد كانت إحداكن في الجاهلية ترمي بالبعرة على رأس الحول ‏"‏‏.‏
      Narrated Um Salama:                          A woman was bereaved of her husband and her relatives worried about      her eyes (which were diseased). They came to Allah's Apostle, and      asked him to allow them to treat her eyes with kohl, but he said, "She     should not apply kohl to her eyes. (In the Pre-Islamic period of      Ignorance) a widowed woman among you would stay in the worst of her      clothes (or the worst part of her house) and when a year had elapsed,      if a dog passed by her, she would throw a globe of dung, Nay, (she      cannot use kohl) till four months and ten days have elapsed."
