Sahih al-Bukhari, Hadith 5334 ⓘ
Narrated Humaid bin Nafi`: Zainab bint Abu Salama told me these three narrations: Zainab said: I went to Um Habiba, the wife of the Prophet when her father, Abu- Sufyan bin Herb had died. Um,Habiba asked for a perfume which contained yellow scent (Khaluq) or some other scent, and she first perfumed one of the girls with it and then rubbed her cheeks with it and said, "By Allah, I am not in need of perfume, but I have heard Allah's Messenger saying, 'It is not lawful for a lady who believes in Allah and the Last Day to mourn for a dead person for more than three days unless he is her husband for whom she should mourn for four months and ten days.'"
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرِ بْنِ مُحَمَّدِ بْنِ عَمْرِو بْنِ حَزْمٍ، عَنْ حُمَيْدِ بْنِ نَافِعٍ، عَنْ زَيْنَبَ ابْنَةِ أَبِي سَلَمَةَ، أَنَّهَا أَخْبَرَتْهُ هَذِهِ الأَحَادِيثَ الثَّلاَثَةَ، قَالَتْ زَيْنَبُ دَخَلْتُ عَلَى أُمِّ حَبِيبَةَ زَوْجِ النَّبِيِّ صلى الله عليه وسلم حِينَ تُوُفِّيَ أَبُوهَا أَبُو سُفْيَانَ بْنُ حَرْبٍ، فَدَعَتْ أُمُّ حَبِيبَةَ بِطِيبٍ فِيهِ صُفْرَةٌ خَلُوقٌ أَوْ غَيْرُهُ فَدَهَنَتْ مِنْهُ جَارِيَةً، ثُمَّ مَسَّتْ بِعَارِضَيْهَا، ثُمَّ قَالَتْ وَاللَّهِ مَا لِي بِالطِّيبِ 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 " .
