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
And the ones of you who are taken up, (i.e., those who die) and leave behind (them) spouses, (the spouses) (i.e., the widows. The following verb is in the feminine plural) shall await by themselves for four months and ten (days); (This is the Iddah "term" for a widowed woman before she can remarry) so, when they have reached their term, then there is no fault in you whatever they perform (with) themselves with beneficence; and Allah is Ever-Cognizant of whatever you do
