وَالَّذِيْنَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُوْنَ اَزْوَاجًا يَّتَرَبَّصْنَ بِاَنْفُسِهِنَّ اَرْبَعَةَ اَشْهُرٍ وَّعَشْرًاۚ فَاِذَا بَلَغْنَ اَجَلَهُنَّ فَلَا جُنَاحَ عَلَيْكُمْ فِيْمَا فَعَلْنَ فِيْٓ اَنْفُسِهِنَّ بِالْمَعْرُوْفِؕ وَاللّٰهُ بِمَا تَعْمَلُوْنَ خَبِيْرٌ ٢٣٤
Translation
As for those of you who die leaving wives, they shall wait by themselves four months and ten days, and when they complete their term, there will be no sin upon you in respect of what they may do with themselves in accordance with honourable norms. And Allah is well aware of what you do.
