[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»  

Zainab said: "So I entered upon Zainab bint Jahsh when her brother died. She called for some perfume and put it on, then said: 'By Allah! I have no need for perfume except that I heard the Messenger of Allah said: "It is not lawful for a woman who believes in Allah and the Last Day to mourn for the dead more than three nights, except for her husband (in which case it is) four months and ten days." (Using translation from Tirmidhī 1196)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمَ الْآخِرِ أَنْ تَحُدَّ عَلَى مَيِّتٍ فَوْقَ ثَلَاثَ لَيَالٍ إِلَّا عَلَى زَوْجٍ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا»  

It is not permissible for a woman believing in Allah and the Hereafter to observe mourning on the dead for more than three (days), except in case of her husband. (Using translation from Muslim 1491)  

عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ تَحُدَّ عَلَى مَيِّتٍ فَوْقَ ثَلَاثٍ إِلَّا عَلَى زَوْجٍ»  

[Machine] I swear to Allah, I have no need for perfume other than that I heard the Messenger of Allah ﷺ say, "It is not permissible for a woman who believes in Allah and the Last Day to mourn for a dead person for more than three nights, except for her husband for four months and ten days." Zainab said, "I entered upon Zainab bint Jahsh when her brother Abdullah ibn Jahsh died, and she called for perfume and applied it. Then she said, "I swear to Allah, I have no need for perfume other than that I heard the Messenger of Allah ﷺ say on the pulpit, "It is not permissible for a woman who believes in Allah and the Last Day to mourn for a dead person for more than three nights, except for her husband for four months and ten days."  

وَاللَّهِ مَا لِي بِالطِّيبِ مِنْ حَاجَةٍ غَيْرَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ تَحُدَّ عَلَى مَيِّتٍ فَوْقَ ثَلَاثِ لَيَالٍ إِلَّا عَلَى زَوْجٍ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا» وَقَالَتْ زَيْنَبُ دَخَلْتُ عَلَى زَيْنَبَ بِنْتِ جَحْشٍ حِينَ تُوُفِّيَ أَخُوهَا عَبْدُ اللَّهِ بْنُ جَحْشٍ فَدَعَتْ بِطِيبٍ فَمَسَّتْ مِنْهُ ثُمَّ قَالَتْ وَاللَّهِ مَا لِي بِالطِّيبِ مِنْ حَاجَةٍ غَيْرَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ عَلَى الْمِنْبَرِ «لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ أَنْ تَحُدَّ عَلَى مَيِّتٍ فَوْقَ ثَلَاثَ لَيَالٍ إِلَّا عَلَى زَوْجٍ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا»  

"I heard my mother, Um Salama saying that a woman came to Messenger of Allah ﷺ and said, "O Messenger of Allah ﷺ! The husband of my daughter has died and she is suffering from an eye disease, can she apply kohl to her eye?" Messenger of Allah ﷺ replied, "No," twice or thrice. (Every time she repeated her question) he said, "No." Then Messenger of Allah ﷺ added, "It is just a matter of four months and ten days. In the Pre-Islamic Period of ignorance a widow among you should throw a globe of dung when one year has elapsed." (Using translation from Bukhārī 5336)  

وَسَمِعْتُ أُمِّي أُمَّ سَلَمَةَ تَقُولُ جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ ابْنَتِي تُوُفِّيَ عَنْهَا زَوْجُهَا وَقَدِ اشْتَكَتْ عَيْنَاهَا فَنُكَحِّلُهَا؟ فَقَالَ رَسُولُ اللَّهِ ﷺ «لَا» مَرَّتَيْنِ أَوْ ثَلَاثًا كُلُّ ذَلِكَ يَقُولُ «لَا إِنَّمَا هِيَ أَرْبَعَةُ أَشْهُرٍ وَعَشْرٌ وَقَدْ كَانَتْ إِحْدَاكُنَّ فِي الْجَاهِلِيَّةِ تَرْمِي بِالْبَعْرَةِ عَلَى رَأْسِ الْحَوْلِ  

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 Prophet ﷺ said: A woman whose husband has died must not wear clothes dyed with safflower (usfur) or with red ochre (mishq) and ornaments. She must not apply henna and collyrium. (Using translation from Abū Dāʾūd 2304)   

عَنِ النَّبِيِّ ﷺ قَالَ «الْمُتَوَفَّى عَنْهَا زَوْجُهَا لَا تَلْبَسُ الْمُعَصْفَرَ مِنَ الثِّيَابِ وَلَا الْمُمَشَّقَةَ وَلَا الْحُلِيَّ وَلَا تَخْتَضِبُ وَلَا تَكْتَحِلُ»
