‘Abdallah b. ‘Umar told that when a man asked God’s messenger what clothing one who was on pilgrimage should wear, he said, “Do not wear shirts, turbans, trousers, garments with head coverings, or shoes, unless one cannot get sandals and wears shoes, in which case he must cut them to come below the ankles; and you must not wear clothing which has any dye of saffron or wars (A plant of a yellow colour in the Yemen, like sesame. The word is also used for the colouring matter which is shaken out when the dower opens)
Bukhari and Muslim. Bukhari added in a version, “A woman who is on pilgrimage must not be veiled, or wear gloves.”
