"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."  

وَسَمِعْتُ أُمَّ سَلَمَةَ تَقُولُ جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ ابْنَتِي تُوُفِّيَ عَنْهَا زَوْجُهَا وَقَدِ اشْتَكَتْ عَيْنَهَا أَفَتَكْحُلُهَا فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ مَرَّتَيْنِ أَوْ ثَلاَثًا كُلَّ ذَلِكَ يَقُولُ لاَ ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا هِيَ أَرْبَعَةُ أَشْهُرٍ وَعَشْرٌ وَقَدْ كَانَتْ إِحْدَاكُنَّ فِي الْجَاهِلِيَّةِ تَرْمِي بِالْبَعَرَةِ عَلَى رَأْسِ الْحَوْلِ  

Zainab said: "And I heard my mother, Umm Salamah said: 'A woman came to the Messenger of Allah and she said: "O Messenger of Allah! My daughter's husband died, and she is suffering from an eye ailment, so can she use Kohl?" the Messenger of Allah said: "No" two or three time. Each time (she asked) he said "no." Then he said: "It is just a mater of four months and ten (days). During Jahliyyah one of you would throw a clump of camel dung when one year passed."  

وَسَمِعْتُ أُمِّي أُمَّ سَلَمَةَ تَقُولُ جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ ابْنَتِي تُوُفِّيَ عَنْهَا زَوْجُهَا وَقَدِ اشْتَكَتْ عَيْنَيْهَا أَفَنَكْحَلُهَا فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ مَرَّتَيْنِ أَوْ ثَلاَثَ مَرَّاتٍ كُلُّ ذَلِكَ يَقُولُ لاَ ثُمَّ قَالَ إِنَّمَا هِيَ أَرْبَعَةُ أَشْهُرٍ وَعَشْرًا وَقَدْ كَانَتْ إِحْدَاكُنَّ فِي الْجَاهِلِيَّةِ تَرْمِي بِالْبَعْرَةِ عَلَى رَأْسِ الْحَوْلِ قَالَ وَفِي الْبَابِ عَنْ فُرَيْعَةَ بِنْتِ مَالِكٍ أُخْتِ أَبِي سَعِيدٍ الْخُدْرِيِّ وَحَفْصَةَ بِنْتِ عُمَرَ  

"A woman from the Quraish came and said: 'O Messenger of Allah, my daughter's eyes are inflamed; shall I apply kohl to her?' (The daughter's) husband had died so (the Prophet) said: 'Not until four months and ten days (have passed).' Then she said: 'I fear for her sight.' He said: 'No, not until four months and ten days (have passed). During the Jahiliyyah one of you would mourn for her husband for a year, then when one year had passed she would throw a piece of dung.'" (Using translation from Nasāʾī 3538)   

يَا رَسُولَ اللهِ إِنَّ ابْنَتِي رَمِدَتْ أَفَأَكْحُلُهَا؟ وَكَانَتْ مُتَوَفًّى عَنْهَا فَقَالَ «إِلَّا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا» ثُمَّ قَالَتْ إِنِّي أَخَافُ عَلَى بَصَرِهَا فَقَالَ «لَا إِلَّا أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا قَدْ كَانَتْ إِحْدَاكُنَّ فِي الْجَاهِلِيَّةِ تُحِدُّ عَلَى زَوْجِهَا سَنَةً ثُمَّ تَرْمِي عَلَى رَأْسِ السَّنَةِ بِالْبَعْرَةِ»
