قَالَتْ زَيْنَبُ فَدَخَلْتُ عَلَى زَيْنَبَ بِنْتِ جَحْشٍ حِينَ تُوُفِّيَ أَخُوهَا فَدَعَتْ بِطِيبٍ فَمَسَّتْ مِنْهُ ثُمَّ قَالَتْ وَاللَّهِ مَا لِي فِي الطِّيبِ مِنْ حَاجَةٍ غَيْرَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ أَنْ تُحِدَّ عَلَى مَيِّتٍ فَوْقَ ثَلاَثِ لَيَالٍ إِلاَّ عَلَى زَوْجٍ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا " .

Zaynab said: I visited Zaynab bint Jahsh when her brother died. She called for perfume and applied some of it. Then she said: By Allah, I have no need for perfume, except that I heard the Messenger of Allah say: It is not lawful for a woman who believes in Allah and the Last Day to mourn a deceased person for more than three nights, except for a husband, for whom the period is four months and ten days.
