Surah Al-Baqarah, Verse 240

وَٱلَّذِينَ يُتَوَفَّوۡنَ مِنكُمۡ وَيَذَرُونَ أَزۡوَٰجٗا وَصِيَّةٗ لِّأَزۡوَٰجِهِم مَّتَٰعًا إِلَى ٱلۡحَوۡلِ غَيۡرَ إِخۡرَاجٖۚ فَإِنۡ خَرَجۡنَ فَلَا جُنَاحَ عَلَيۡكُمۡ فِي مَا فَعَلۡنَ فِيٓ أَنفُسِهِنَّ مِن مَّعۡرُوفٖۗ وَٱللَّهُ عَزِيزٌ حَكِيمٞ٢٤٠

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. And Allāh is Exalted in Might and Wise.
