"Also (forbidden are) women already married, except those whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek them from your property, desiring chastity, not fornication. So with those among them whom you have enjoyed, give them their required due, but if you agree mutually after the requirement (has been determined), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise." - Quran 4:24 (read more)

He said, "This is the deficiency in her religion." - Sahih Bukhari 1:6:301 (read more)

"One of the husband's rights is to discipline his wife if she is disobedient. What does the word 'disobedience' mean? Disobedience is to leave the house without the husband's permission, to refuse to obey the husband in bed, to speak to the husband impolitely, or to do the opposite of what he likes. All these are forms of disobedience..." - Galal Al-Khatib
