"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)

"Narrated Anas bin Malik: Allah's Apostle said, "You should listen to and obey, your ruler even if he was an Ethiopian (black) slave whose head looks like a raisin." - Sahih Bukhari 9:89:256 (read more)

"Even if they [kafir] give you some of your rights by treating you nicely, they do not give Allaah His rights and they do not give the Qur’aan its rights and they do not give our Prophet (peace and blessings of Allaah be upon him) his rights. The rights of Allaah and His Book and His Prophet are more important than our personal rights. Remember this, for this is one of the things that will help you to hate them and regard them as enemies until they believe in Allaah alone." - Islam Q&A
