20. And if you desire to change one wife for another and you have already given her a heap of treasure; then take not anything thereof. Will you take it by slander and with manifest sin?

21. How you shall take it when each of you has already become unveiled before one another and they have taken from you a most firm covenant?

22. And do not marry those women whom your fathers have married, except what has already passed. Undoubtedly, that is an act of indecency and wrath and an evil way.

SECTION: 4

23. Forbidden to you are your mothers, and your daughters and sisters and your father's sisters and mother's sisters and your brother's daughters and your sister's daughters, and your mothers who have given suck to you and your foster sisters and the mothers of your wives and daughters (your step daughters) who are in your care from the wives with whom you had intercourse but if you had not intercourse with them, then there is no harm in their daughters, and the wives of your sons who are of your loins and to have two sisters together except what has already passed. Undoubtedly. Allah is Forgiving, Merciful.
