The Prophet ﷺ said, "It is not lawful for a lady who believes in Allah and the Last Day, to mourn for more than three days for a dead person, except for her husband, in which case she should neither put kohl in her eyes, nor perfume herself, nor wear dyed clothes, except a garment of 'Asb"  

قَالَ النَّبِيُّ ﷺ لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ أَنْ تُحِدَّ فَوْقَ ثَلاَثٍ إِلاَّ عَلَى زَوْجٍ فَإِنَّهَا لاَ تَكْتَحِلُ وَلاَ تَلْبَسُ ثَوْبًا مَصْبُوغًا إِلاَّ ثَوْبَ عَصْبٍ  

'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  

'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.’” (Using translation from Ibn Mājah 2087)  

قَالَ رَسُولُ اللهِ ﷺ لَا يُحِدُّ عَلَى مَيِّتٍفَوْقَ ثَلَاثٍ إِلَّا الْمَرْأَةُ فَإِنَّهَا تُحِدُّ عَلَى زَوْجِهَا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا لَا تَلْبَسُ ثَوْبًا مَصْبُوغًا إِلَّا ثَوْبَ عَصْبٍ وَلَا تَكْتَحِلُ وَلَا تَطَّيَّبُ إِلَّا عِنْدَ أَدْنَى طُهْرَتِهَا نُبْذَةً مِنْ قُسْطٍ وَأَظْفَارٍ  

I had in fact no need of it, but I heard Messenger of Allah ﷺ as saying: It is not permissible for the women believing in Allah and the Hereafter to abstain from adornment beyond three days except (at the death of) husband (in which case she must abstain from adornment) for four months and ten days. (Using translation from Muslim 1486d)  

قَالَ رَسُولُ اللَّهِ ﷺ «لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ تَحُدَّ عَلَى مَيِّتٍ فَوْقَ ثَلَاثٍ إِلَّا عَلَى زَوْجٍ فَإِنَّهَا تَحُدُّ عَلَيْهِ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا لَا تَكْتَحِلُ وَلَا تَلْبَسُ ثَوْبًا مَصْبُوغًا إِلَّا ثَوْبَ عَصْبٍ وَلَا تَمَسُّ طِيبًا إِلَّا عِنْدَ أَدْنَى طُهْرِهَا إِذَا اغْتَسَلَتْ مِنْ مَحِيضِهَا نُبْذَةَ قُسْطٍ وَأَظْفَارٍ» *  

"The Messenger of Allah said: 'No woman should mourn for anyone who dies for more than three days, except for a husband, for whom she should mourn for four months and ten days. She should not wear garments that are dyed or patterned, or put on kohl or comb her hair, and she should not put on any perfume except when purifying herself after her period, when she may use a little of Qust or Azfar.'" (Using translation from Nasāʾī 3534)  

قَالَ رَسُولُ اللهِ ﷺ «لَا تُحِدُّ امْرَأَةٌ عَلَى مَيِّتٍ فَوْقَ ثَلَاثٍ إِلَّا عَلَى زَوْجٍ فَإِنَّهَا تُحِدُّ عَلَيْهِ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا وَلَا تَلْبَسُ ثَوْبًا مَصْبُوغًا إِلَّا ثَوْبَ عَصْبٍ وَلَا تَكْتَحِلُ وَلَا تَمْتَشِطُ وَلَا تَمَسُّ طِيبًا إِلَّا عِنْدَ طُهْرِهَا حِينَ تَطْهُرُ نُبِذَ مِنْ قُسْطٍ وَأَظْفَارٍ»
