Abu Bakr b. ‘Abd ar-Rahman told that when God’s Messenger married Umm Salama he said to her in the morning, “You are not being humbled in my estimation. If you wish I shall stay with you seven nights as I did with my other wives, but if you wish I shall stay three and then visit my wives in turn.” She replied, “Stay three nights.” In a version he said, “The virgin gets seven nights and the woman who has had a previous husband three.” Muslim transmitted it.
وَعَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِين تَزَوَّجَ أُمَّ سَلَمَةَ وَأَصْبَحَتْ عِنْدَهُ قَالَ لَهَا: «لَيْسَ بِكِ عَلَى أَهْلِكِ هَوَانٌ إِنْ شِئْتِ سَبَّعْتُ عِنْدَكِ وَسَبَّعْتُ عِنْدَهُنَّ وَإِنْ شِئْتِ ثَلَّثْتُ عِنْدَكِ وَدُرْتُ» . قَالَتْ: ثَلِّثْ. وَفِي رِوَايَةٍ: إِنَّهُ قَالَ لَهَا: «لِلْبِكْرِ سَبْعٌ وَلِلثَّيِّبِ ثَلَاثٌ» . رَوَاهُ مُسلم
