Widows
Those among you who die and leave behind wives should provide for them with a year’s maintenance and residence. But if they choose to leave, there is no blame upon them for what they do within reason.
2:240(In the case of) those of you who are about to die and leave behind them wives, they should bequeath unto their wives a provision for the year without turning them out, but if they go out (of their own accord) there is no sin for you in that which they do of themselves within their rights. Allah is Mighty, Wise.
