(You Shall Observe the Pre-Marriage Interims)
Those who die and leave wives, their widows shall wait four months and ten days (before they remarry). Once they fulfill their interim, you commit no error by letting them do whatever righteous matters they wish to do. God is fully Cognizant of everything you do.
وَالَّذينَ يُتَوَفَّونَ مِنكُم وَيَذَرونَ أَزوٰجًا يَتَرَبَّصنَ بِأَنفُسِهِنَّ أَربَعَةَ أَشهُرٍ وَعَشرًا فَإِذا بَلَغنَ أَجَلَهُنَّ فَلا جُناحَ عَلَيكُم فيما فَعَلنَ فى أَنفُسِهِنَّ بِالمَعروفِ وَاللَّهُ بِما تَعمَلونَ خَبيرٌ
