Surah Al-Baqara Verse 234 - English Translation by Aisha Bewley
Surah Al-Baqaraوَٱلَّذِينَ يُتَوَفَّوۡنَ مِنكُمۡ وَيَذَرُونَ أَزۡوَٰجٗا يَتَرَبَّصۡنَ بِأَنفُسِهِنَّ أَرۡبَعَةَ أَشۡهُرٖ وَعَشۡرٗاۖ فَإِذَا بَلَغۡنَ أَجَلَهُنَّ فَلَا جُنَاحَ عَلَيۡكُمۡ فِيمَا فَعَلۡنَ فِيٓ أَنفُسِهِنَّ بِٱلۡمَعۡرُوفِۗ وَٱللَّهُ بِمَا تَعۡمَلُونَ خَبِيرٞ
Those of you who die leaving wives behind: they should wait by themselves for four months and ten nights. When their ´idda comes to an end, you are not to blame for anything they do with themselves with correctness and courtesy. Allah is aware of what you do
