وَحَدَّثَنَاهُ أَبُو غَسَّانَ الْمِسْمَعِيُّ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا عَبْدُ الْوَهَّابِ، قَالَ سَمِعْتُ يَحْيَى بْنَ سَعِيدٍ، يَقُولُ سَمِعْتُ نَافِعًا، يُحَدِّثُ عَنْ صَفِيَّةَ بِنْتِ أَبِي عُبَيْدٍ، أَنَّهَا سَمِعَتْ حَفْصَةَ بِنْتَ عُمَرَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم تُحَدِّثُ عَنِ النَّبِيِّ صلى الله عليه وسلم بِمِثْلِ حَدِيثِ اللَّيْثِ وَابْنِ دِينَارٍ وَزَادَ ‏ “‏ فَإِنَّهَا تُحِدُّ عَلَيْهِ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا ‏”‏ ‏.‏ Safiyya bint Abu ‘Ubaid reported that she heard Hafsa daughter of Umar (Allah be pleased with them), (and) wife of Allah’s Prophet (may peace be upon him), narrating a hadith like this from Allah’s Apostle (may peace be upon him), and she made this addition: ” She should abstain from adorning herself (in case of the death of her husband) for four months and ten days.” Chain : Malik bin Abd al-Wahd – Muhammad bin al-Muthna – al-Zaman – ‘Abdul Wahab bin ‘Abdul Majeed al-Thaqaf – Yahya bin Sa’id al-Ansari – Nafie’ – Safiyya
