Umm Salama and Umm Habiba (Allah be pleased with them) were talking with each other (and saying) that a woman came to Messenger of Allah ﷺ and mentioned to him that her daughter had lost her husband, and her eyes were sore and she wanted to use collyrium, whereupon Messenger of Allah ﷺ said: One among you used to throw dung at the end of a year, and now (this abstinence from adornment) is only for four months and ten days.
أَنَّ امْرَأَةً أَتَتْ رَسُولَ اللَّهِ ﷺ فَذَكَرَتْ لَهُ أَنَّ بِنْتًا لَهَا تُوُفِّيَ عَنْهَا زَوْجُهَا فَاشْتَكَتْ عَيْنُهَا فَهْىَ تُرِيدُ أَنْ تَكْحُلَهَا فَقَالَ رَسُولُ اللَّهِ ﷺ قَدْ كَانَتْ إِحْدَاكُنَّ تَرْمِي بِالْبَعَرَةِ عِنْدَ رَأْسِ الْحَوْلِ وَإِنَّمَا هِيَ أَرْبَعَةُ أَشْهُرٍ وَعَشْرٌ
