2:240
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 حَكِيمٞ ٢٤٠
Wa Al-Ladhīna Yutawaffawna Minkum Wa Yadharūna 'Azwājāan Waşīyatan Li'zwājihim Matā`āan 'Ilá Al-Ĥawli Ghayra ۚ 'Ikhrājin Fa'in Kharajna Falā Junāĥa `Alaykum Fī Mā Fa`alna Fī 'Anfusihinna Min ۗ Ma`rūfin Wa Allāhu `Azīzun Ĥakīmun
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 Allah is Exalted in Might and Wise.
