[Machine] The Messenger of Allah ﷺ said, "It is not permissible for a believing woman in Allah and the Last Day to mourn for more than three days except for her husband. In that case, she should mourn for four months and ten days."

قَالَ رَسُولُ اللَّهِ ﷺ «لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ تَحُدَّ عَلَى هَالِكٍ أَكْثَرِ مِنْ ثَلَاثٍ إِلَّا عَلَى زَوْجٍ فَإِنَّهَا تَحُدُّ عَلَيْهِ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا»
