قَالَتْ زَيْنَبُ ثُمَّ دَخَلْتُ عَلَى زَيْنَبَ بِنْتِ جَحْشٍ حِينَ تُوُفِّيَ أَخُوهَا وَقَدْ دَعَتْ بِطِيبٍ وَمَسَّتْ مِنْهُ ثُمَّ قَالَتْ وَاللَّهِ مَا لِي بِالطِّيبِ مِنْ حَاجَةٍ غَيْرَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ عَلَى الْمِنْبَرِ " لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ تَحِدُّ عَلَى مَيِّتٍ فَوْقَ ثَلاَثِ لَيَالٍ إِلاَّ عَلَى زَوْجٍ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا " .
Zainab said: 'Then I visited Zainab bint Jahsh when her brother died. She called for perfume and applied some. She said: By Allah, I have no need for perfume; I only did this because I heard the Messenger of Allah say from the pulpit: A woman who believes in Allah and the Last Day may not mourn for anyone for more than three days, except for her husband, for whom the mourning period is four months and ten days.'
