Wearing Non-pure Silk Garments
Is it permissible for men to wear clothes that are made of pure silk and partially from other non-silk materials (e.g., 50% silk and 50% other fibers) since some scholars have stated that it is allowed for men to wear garments containing four fingers’ width of silk, because of the Hadith reported by `Umar Ibn Al-Khattab, may Allah be pleased with him, who said that the Prophet, peace and blessings be upon him, has forbidden the wearing of silk except for an area whose width is of two fingers, three or four. (Reported by Muslim, 3/1644)
