Hadith 12:77
'Abd al-Malik b. Abi Bakr reported from his father on the authority of Umm Salamah:
When the Messenger of Allah (ﷺ) married Umm Salamah, he stayed with her three night, and said: Your people (i.e. clan) are not being humbled for you in my estimation. If you wish I shall stay with you seven nights; and if I stay with you seven nights, I shall stay with my other wives seven nights.
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ أَبِي بَكْرٍ، عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي بَكْرٍ، عَنْ أَبِيهِ، عَنْ أُمِّ سَلَمَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَمَّا تَزَوَّجَ أُمَّ سَلَمَةَ أَقَامَ عِنْدَهَا ثَلاَثًا ثُمَّ قَالَ " لَيْسَ بِكِ عَلَى أَهْلِكِ هَوَانٌ إِنْ شِئْتِ سَبَّعْتُ لَكِ وَإِنْ سَبَّعْتُ لَكِ سَبَّعْتُ لِنِسَائِي "
