Disciplining By Hitting
Umar Ibn Al-Khattab used this method and was famous for carrying his stick with which he struck people. He struck some of the governors because of some deeds that they committed. During Umar's vist to Syria, he entered the house of one of his governors and found they had too many possession's. 'Umar got angry and started hitting them with his stick.

Narrated Abd Al-A’laa from Mo’ammar from Al-Zuhri from Anas. (Al-Albani: I say: This chain is Authentic, if Al-Zuhri heard it from Anas) Narrated Alee Ibn Mos’har from Al-Mokhtar Ibn Folfol from Anas Ibn Malik who said: A slave girl of Muhajirin or Ansaar came to Umar wearing Jilbab (complete Hijab), he said: "Have you been freed?" She said: “No!” He said: “Put it off your head!” Jilbab is for the freed women. So she hesitated, so he got up to her with the whip (Darrah), and he hit her on the head, until she threw it.

This narration is authentic. However, notice it states a slave woman is not required to cover herself during prayer whereas the books of the opponents state the slave girl is not required to cover her head in front of the public. In addition, there is no mention of the Imam (a.s) hitting the slave girl in this narration.
