Sahih Muslim 1460c
Abu Bakr b. 'Abd al-Rahman reported that when Messenger of Allah ﷺ married Umm Salama and he visited her, and when he intended to come out, she caught hold of his cloth. whereupon Messenger of Allah ﷺ said: If you so desire, I can extend the time (of my stay) with you, but then I shall have to calculate the time (that I stay with you and shall have to spend the same time with other wives). For the virgin woman, (her husband has to stay with her) for a week, and for the woman previously married it is three days.
وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ بِلاَلٍ - عَنْ عَبْدِ، الرَّحْمَنِ بْنِ حُمَيْدٍ عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي بَكْرٍ، عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّ رَسُولَ اللَّهِ ﷺ حِينَ تَزَوَّجَ أُمَّ سَلَمَةَ فَدَخَلَ عَلَيْهَا فَأَرَادَ أَنْ يَخْرُجَ أَخَذَتْ بِثَوْبِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنْ شِئْتِ زِدْتُكِ وَحَاسَبْتُكِ بِهِ لِلْبِكْرِ سَبْعٌ وَلِلثَّيِّبِ ثَلاَثٌ" .
