“Abu ‘Abd Allah (a.s.), has said, ‘It is permissible for a man to apply dye to his hairs and experience sexual relation with dye applied. It is permissible for a man to apply lime to his hairs and experience sexual relation or draw blood from his body by means of cupping or slaughter (an animal for food). He should not taste anything before washing his hands and rinsing his mouth because of fear of the appearance of abnormal whiteness in his skin.’”
