وَٱلَّذِينَ يُتَوَفَّوْنَ مِنكُمْ وَيَذَرُونَ أَزْوَٰجًا وَصِيَّةً لِّأَزْوَٰجِهِم مَّتَٰعًا إِلَى ٱلْحَوْلِ غَيْرَ إِخْرَاجٍ ۚ فَإِنْ خَرَجْنَ فَلَا جُنَاحَ عَلَيْكُمْ فِى مَا فَعَلْنَ فِىٓ أَنفُسِهِنَّ مِن مَّعْرُوفٍ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ

And those of you who die and leave wives behind, (make) a bequest in favor of their wives of maintenance for a year without turning (them) out, then if they themselves go away, there is no blame on you for what they do of lawful deeds by themselves, and Allah is Mighty, Wise.
