Umar, the Slave and the Veil

Musannaf Ibn Abi Shaybah 6382, 6383

6382. Narrated Anas ibn Malik:

Umar saw a slave-girl wearing a veil, so he struck her. He said: "Do not emulate free women."

6383. Narrated Anas ibn Malik:

A female slave came to Umar ubn al-Khattab. He knew her through some of the emigrants, or the Ansar. She was wearing a Jilbab (cloak) which veiled her. He asked her: "Have you been freed?" She said: "No." He said: "What about the Jilbab? Pull it down off your head. The Jilbab is only for free women from among the believing women." She hesitated. So he came at her with a whip and struck her on the head, until she cast it off her head.
