And all married women (are forbidden unto you), save such as your right hands possess (captives of war) - It is a decree of Allah for you. But lawful for you are all beyond these. So seek them with your wealth in honest marriage and not lust. But such of them from whom you seek comfort, give them their portions as a duty; and there is no crime in what you do by mutual agreement after the duty has been done. Verily, Allah is ever Knower and Wise.
