What is the minimum mandatory for every men to bequest for his wife whether he is rich or poor?

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

Those of you who die leaving behind your wives should make testament of one year’s provision without expulsion in favour of your wives; and if they themselves depart, there shall be no blame upon you for what they may do with themselves in an honourable manner. Allah is All-Mighty, All-Wise.

Tum mein se jo log wafaat payein aur pichey biwiyan chodh rahey hon, unko chahiye ke apni biwiyon ke haqq mein yeh wasiyat kar jayein ke ek saal tak unko naan-o-nafaqa (maintenance) diya jaye aur woh ghar se na nikali jayein. Phir agar woh khud nikal jayein to apni zaat ke maamle mein maroof tareeqe se woh jo kuch bhi karein uski koi zimmedari tumpar nahin hai. Allah sab par gaalib iqtedar rakhne wala aur hakeem o daana hai
