سورة البقرة · 2:240

240. 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.
