Quran

 2:234

وَالَّذِينَ يُتَوَفَّوْنَ مِنْكُمْ وَيَذَرُونَ أَزْوَاجًا يَتَرَبَّصْنَ بِأَنْفُسِهِنَّ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا ۖ فَإِذَا بَلَغْنَ أَجَلَهُنَّ فَلَا جُنَاحَ عَلَيْكُمْ فِيمَا فَعَلْنَ فِي أَنْفُسِهِنَّ بِالْمَعْرُوفِ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ ﴿٢٣٤﴾

234. As for those among you who die and leave widows behind, they shall wait by themselves for four months and ten days. When they have reached their term, there is no blame on you regarding what they might honorably do with themselves. Allah is aware of everything you do.
