Forbidden to you are your mothers, your daughters, your sisters, your father's sisters and your mother's sisters, your brother's daughters and your sister's daughters, your milk-mothers, your milk-sisters, the mothers of your wives, and the stepdaughters - who are your foster-children, born of your wives with whom you have consummated the marriage; but if you have not consummated the marriage with them, there will be no blame upon you (if you marry their daughters). It is also forbidden for you to take the wives of the sons who have sprung from your loins and to take two sisters together in marriage, although what is past is past. Surely Allah is All-Forgiving, All-Compassionate.
