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.1 And Allāh is Exalted in Might and Wise.
Translation: Saheeh International (English)
1 This directive was abrogated by those later revealed in 2:234 and 4:12.
Those of you that pass away leaving behind wives must make a bequest for them to be provided with accommodation and maintenance for a period of one year in which your heirs may not remove them. This is to make up for the loss they have suffered and in respect for the deceased. If they leave before the end of the year by their own choice, there will be no sin on either you or them for what they do with themselves in terms of their beautification. Allah is Mighty and none can overpower Him. He is Wise in His planning and legislation. It should be noted that most commentators are of the view that the law contained in this verse has been abrogated by the verse: ‘When someone passes away and leaves behind a wife who is not pregnant, it is the duty of these women to wait for a period of four months and ten days...’ [ Sūrah Al-Baqarah: 234].
