the Prophet ﷺ said: "It is not permissible for a woman to mourn for any deceased person for more than three days, except for her husband."  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَحِلُّ لاِمْرَأَةٍ أَنْ تُحِدَّ عَلَى مَيِّتٍ فَوْقَ ثَلاَثٍ إِلاَّ عَلَى زَوْجٍ  

the Messenger of Allah ﷺ, said: "It is not permissible for a woman who believes in Allah and the Last Day to mourn for any deceased person for more than three days, except for her husband."  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ أَنْ تُحِدَّ عَلَى مَيِّتٍ فَوْقَ ثَلاَثٍ إِلاَّ عَلَى زَوْجٍ  

'No deceased person should be mourned for more than three days, except a woman should mourn for her husband for four months and ten days, and she should not wear dyed clothes, except for a garment of 'Asb, and she should not wear kohl or perfume, except at the beginning of her purity, when she may apply a little Qust and Azfar.’”  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تُحِدُّ عَلَى مَيِّتٍ فَوْقَ ثَلاَثٍ إِلاَّ الْمَرْأَةُ تُحِدُّ عَلَى زَوْجِهَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا وَلاَ تَلْبَسُ ثَوْبًا مَصْبُوغًا إِلاَّ ثَوْبَ عَصْبٍ وَلاَ تَكْتَحِلُ وَلاَ تَطَيَّبُ إِلاَّ عِنْدَ أَدْنَى طُهْرِهَا بِنُبْذَةٍ مِنْ قُسْطٍ وَأَظْفَارٍ
