وَالَّذِيۡنَ يُتَوَفَّوۡنَ مِنۡكُمۡ وَيَذَرُوۡنَ اَزۡوَاجًا يَّتَرَبَّصۡنَ بِاَنۡفُسِهِنَّ اَرۡبَعَةَ اَشۡهُرٍ وَّعَشۡرًاۚ فَاِذَا بَلَغۡنَ اَجَلَهُنَّ فَلَا جُنَاحَ عَلَيۡكُمۡ فِيۡمَا فَعَلۡنَ فِيۡ٘ اَنۡفُسِهِنَّ بِالۡمَعۡرُوۡفِؕ وَاللّٰهُ بِمَا تَعۡمَلُوۡنَ خَبِيۡرٌ

And when they have fulfilled their term, then there is no blame upon you for what they do with themselves in an acceptable manner. And Allah is [fully] Acquainted with what you do
