that when Saudah bint Zam'ah grew old, she gave her day to 'Aishah, and the Messenger of Allah went to 'Aishah on Saudah's day.  

أَنْ كَبِرَتْ سَوْدَةُ بِنْتُ زَمْعَةَ وَهَبَتْ يَوْمَهَا لِعَائِشَةَ فَكَانَ رَسُولُ اللَّهِ ﷺ يَقْسِمُ لِعَائِشَةَ بِيَوْمِ سَوْدَةَ  

that the Messenger of Allah became angry with Safiyyah bint Huyai for something, and Safiyyah said: "O 'Aishah, can you make the Messenger of Allah be pleased with me, and I will give you my day?" She said: "Yes." So she took a headcover of hers that was dyed with saffron and sprinkled it with water so that its fragrance would become stronger, then she sat beside the Messenger of Allah. The Prophet said: "O 'Aishah, go away, because it is not your day!" She said: "That is the Grace of Allah which He bestows on whom He pleases." Then she told him about that matter and he was pleased with her.  

أَنَّ رَسُولَ اللَّهِ ﷺ وَجَدَ عَلَى صَفِيَّةَ بِنْتِ حُيَىٍّ فِي شَىْءٍ فَقَالَتْ صَفِيَّةُ يَا عَائِشَةُ هَلْ لَكِ أَنْ تُرْضِي رَسُولَ اللَّهِ ﷺ عَنِّي وَلَكِ يَوْمِي قَالَتْ نَعَمْ فَأَخَذَتْ خِمَارًا لَهَا مَصْبُوغًا بِزَعْفَرَانٍ فَرَشَّتْهُ بِالْمَاءِ لِيَفُوحَ رِيحُهُ ثُمَّ قَعَدَتْ إِلَى جَنْبِ رَسُولِ اللَّهِ ﷺ فَقَالَ النَّبِيُّ ﷺ يَا عَائِشَةُ إِلَيْكِ عَنِّي إِنَّهُ لَيْسَ يَوْمَكِ فَقَالَتْ ذَلِكَ فَضْلُ اللَّهِ يُؤْتِيهِ مَنْ يَشَاءُ فَأَخْبَرَتْهُ بِالأَمْرِ فَرَضِيَ عَنْهَا  

"This Verse 'And making peace is better.' was revealed concerning a man who had been married to a woman for a long time, and she had given birth to his children and he wanted to exchange her (for a new wife). She agreed that he would stay with her (the new wife) and would not give her (the first wife) a share of his time. (i.e.) not spend the nights with her)."  

أَنَّهَا قَالَتْ نَزَلَتْ هَذِهِ الآيَةُ {وَالصُّلْحُ خَيْرٌ} فِي رَجُلٍ كَانَتْ تَحْتَهُ امْرَأَةٌ قَدْ طَالَتْ صُحْبَتُهَا وَوَلَدَتْ مِنْهُ أَوْلاَدًا فَأَرَادَ أَنْ يَسْتَبْدِلَ بِهَا فَرَاضَتْهُ عَلَى أَنْ تُقِيمَ عِنْدَهُ وَلاَ يَقْسِمَ لَهَا
