Al-Baqara 2:240

Those of you who pass away leaving widows should bequeath in their favor to be maintained for one year without forcing them out[134]. But if they leave, then there is no blame on you for what they reasonably do with themselves. And Allah is All-Mighty, All-Wise.

[134] The provision of this verse has been abrogated by verse 4:12.

And those who are taken in death among you and leave wives behind - for their wives is a bequest: maintenance for one year without turning [them] out. But if they leave [of their own accord], then there is no blame upon you for what they do with themselves in an acceptable way.[96] And Allāh is Exalted in Might and Wise.

[96] This directive was abrogated by those later revealed in 2:234 and 4:12.

240. And those of you who die and leave behind wives should bequeath for their wives a year’s maintenance and residence without turning them out, but if they (wives) leave, there is no sin on you for that which they do of themselves, provided it is honourable (e.g. lawful marriage). And Allâh is All-Mighty, All-Wise[64].

[64] (V.2:240): The provision of this Verse has been abrogated by Verse (4:12)

(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.
