Yahya related to me from Malik from Nafic that Saffiyya bint AbiUbayd suffered from an eye-complaint while she was in mourning for herhusband, Abdullah ibn Umar. She did not apply kohl until her eyesalmost had ramas (a dry white secretion in the corners of the eye).Malik said, "A woman whose husband has died should anoint hereyes with olive oil and sesame oil and the like of that since there isno perfume in it."Malik said, "A woman in mourning for herhusband should not put on any jewellery - rings, anklets, or such-like, neither should she dress in any sort of colourful, stripedgarment unless it is coarse. She should not wear any cloth dyed withanything except black, and she should only dress her hair with thingslike lotus-tree leaves which do not dye the hair."
