Sūrah Al-Baqara · The Cow2 : 240
وَٱلَّذِینَ یُتَوَفَّوۡنَ مِنكُمۡ وَیَذَرُونَ أَزۡوَ ٰجࣰا وَصِیَّةࣰ لِّأَزۡوَ ٰجِهِم مَّتَـٰعًا إِلَى ٱلۡحَوۡلِ غَیۡرَ إِخۡرَاجࣲۚ فَإِنۡ خَرَجۡنَ فَلَا جُنَاحَ عَلَیۡكُمۡ فِی مَا فَعَلۡنَ فِیۤ أَنفُسِهِنَّ مِن مَّعۡرُوفࣲۗ وَٱللَّهُ عَزِیزٌ حَكِیمࣱ
“(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.”
