وَالَّذينَ يُتَوَفَّونَ مِنكُم وَيَذَرونَ أَزواجًا وَصِيَّةً لِأَزواجِهِم مَتاعًا إِلَى الحَولِ غَيرَ إِخراجٍ ۚ فَإِن خَرَجنَ فَلا جُناحَ عَلَيكُم في ما فَعَلنَ في أَنفُسِهِنَّ مِن مَعروفٍ ۗ وَاللَّهُ عَزيزٌ حَكيمٌ

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.
