Surah Al-Baqarah (The Cow), Verse 240

وَالَّذِیْنَ یُتَوَفَّوْنَ مِنْكُمْ وَیَذَرُوْنَ اَزْوَاجًا وَّصِیَّةً لِّاَزْوَاجِهِمْ مَّتَاعًا اِلَی الْحَوْلِ غَیْرَ اِخْرَاجٍ فَاِنْ خَرَجْنَ فَلَا جُنَاحَ عَلَیْكُمْ فِیْ مَا فَعَلْنَ فِیْۤ اَنْفُسِهِنَّ مِنْ مَّعْرُوْفٍ وَاللّٰهُ عَزِیْزٌ حَكِیْمٌ ۟

Wallazeena yutawaf fawna minkum wa yazaroona azwaajanw wasiyyatal li azwaajihim mataa'an ilal hawlighaira ikhraaj; fa in kharajna falaa junaaha 'alaikum fee maa fa'alna feee anfusihinna min ma'roof; wallaahu Azeezun Hakeem

“Those of you who die and leave widows should bequeath for their widows a year's maintenance and residence; but if they leave (The residence), there is no blame on you for what they do with themselves, provided it is reasonable. And Allah is Exalted in Power, Wise.”
