"Fight those who believe not in Allah or the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the jizya with willing submission, and feel themselves subdued." - Quran 9:29 (read more)

"Narrated Kurib: the freed slave of Ibn 'Abbas, that Maimuna bint Al-Harith told him that she manumitted a slave-girl without taking the permission of the Prophet. On the day when it was her turn to be with the Prophet, she said, "Do you know, O Allah's Apostle, that I have manumitted my slave-girl?" He said, "Have you really?" She replied in the affirmative. He said, "You would have got more reward if you had given her (i.e. the slave-girl) to one of your maternal uncles." - Sahih Bukhari 3:47:765 (read more)

"If he beats her, the beatings should not be hard, so that they do not leave a mark. He can beat her with a short rod. He must avoid beating her in the face or in places in the head where it hurts. The beatings should be on the body and should not come one right after the other. These are all choices made during the process, but beatings are allowed only as a last resort. The honoring of the wife in Islam is also evident in the fact that the punishment of beating is permissible in one case only: when she refuses to sleep with him." - Sa’d Arafat
