Sahih Muslim | Book 24 | Hadith Number 5150

Narrated by Khalifa b. Ka'b AbCi Dhubyan
Khalifa b. Ka'b AbCi Dhubyan reported: I heard 'Abdullah b. Zubair addressing the people and saying: Behold! do not dress your women with silk clothes for I heard 'Umar b. Khattab as saying that he had heard Allah's messenger(may peace be upon him) as saying: Do not wear silk, for one who wear it in this world will not wear it in the Hereafter.
