527 Among many nations, including Arabs in the Days of Ignorance, a step-son or brother took possession of a dead man's widow or widows along with his goods and chattels. This shameful custom is forbidden. See also 4:22 below.
528 Another trick, to detract from the freedom of married women was to treat them badly and force them to sue for a Khul'divorce (see 2:229, n. 258) or its equivalent in pre-Islamic custom, when the dower could be claimed back. This is also forbidden. Or the harshness may be exercised in another way; a divorced woman may be prevented by those who have control of her, from re-marrying unless she remits her dower. All kinds of harshness are forbidden.

7 For example, a man would prevent a female relative (such as his sister or mother) from getting married so he can secure her estate for himself.
