There is no lack of estimation on the part of your husband for you. If you wish I can stay with you for a week, but in case I stay with you for a week, then I shall have to stay for a week with all my wives.  

أَنَّ رَسُولَ اللَّهِ ﷺ لَمَّا تَزَوَّجَ أُمَّ سَلَمَةَ أَقَامَ عِنْدَهَا ثَلاَثًا وَقَالَ إِنَّهُ لَيْسَ بِكِ عَلَى أَهْلِكِ هَوَانٌ إِنْ شِئْتِ سَبَّعْتُ لَكِ وَإِنْ سَبَّعْتُ لَكِ سَبَّعْتُ لِنِسَائِي  

There is no lack of estimation for you on the part of your husband. So if you desire I can spend a week with you, and if you like I may spend three (nights). and then I will visit you in turn. She said: Spend three (nights).  

أَنَّ رَسُولَ اللَّهِ ﷺ حِينَ تَزَوَّجَ أَمَّ سَلَمَةَ وَأَصْبَحَتْ عِنْدَهُ قَالَ لَهَا لَيْسَ بِكِ عَلَى أَهْلِكِ هَوَانٌ إِنْ شِئْتِ سَبَّعْتُ عِنْدَكِ وَإِنْ شِئْتِ ثَلَّثْتُ ثُمَّ دُرْتُ قَالَتْ ثَلِّثْ  

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.  

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  

A hadith like this has been narrated on the authority of Ibn Humaid.  

عَنْ عَبْدِ الرَّحْمَنِ بْنِ حُمَيْدٍ بِهَذَا الإِسْنَادِ مِثْلَهُ  

If you desire that I spend a week with you, I shall have to spend a week with my (other) wives, and if spend a week with you, I shall have to spend a week with my (other) wives.  

عَنْ أُمِّ سَلَمَةَ ذَكَرَ أَنَّﷺ تَزَوَّجَهَا وَذَكَرَ أَشْيَاءَ هَذَا فِيهِ قَالَ إِنْ شِئْتِ أَنْ أُسَبِّعَ لَكِ وَأُسَبِّعَ لِنِسَائِي وَإِنْ سَبَّعْتُ لَكِ سَبَّعْتُ لِنِسَائِي  

When anyone who has already a wife marries virgin, he should stay with her for seven nights (and then turn to his other wife), but when anyone having a virgin with him (as his wife) marries a woman who has been previously married he should stay with her for three nights. Khalid (one of the narrators) said. If I were to say that it could be directly traced to the Prophet ﷺ. I would have told the truth, but he (Hadrat Anas) said: Such is the tradition.  

إِذَا تَزَوَّجَ الْبِكْرَ عَلَى الثَّيِّبِ أَقَامَ عِنْدَهَا سَبْعًا وَإِذَا تَزَوَّجَ الثَّيِّبَ عَلَى الْبِكْرِ أَقَامَ عِنْدَهَا ثَلاَثًا قَالَ خَالِدٌ وَلَوْ قُلْتُ إِنَّهُ رَفَعَهُ لَصَدَقْتُ وَلَكِنَّهُ قَالَ السُّنَّةُ كَذَلِكَ  

It is the Sunnah to stay with a virgin (after having married her) for a week. Khalid (one of the narrators) said: If wish I can say that it can be traced up to the Prophet ﷺ.  

خَالِدٌ وَلَوْ شِئْتُ قُلْتُ رَفَعَهُ إِلَى النَّبِيِّ ﷺ
