[Machine] When Sawdah bint Zam'ah became old, she gifted her day to Aisha. So the Prophet ﷺ would divide his day between Aisha and Sawdah.
«لَمَّا كَبُرَتْ سَوْدَةُ بِنْتُ زَمْعَةَ فَوَهَبَتْ يَوْمَهَا لِعَائِشَةَ فَكَانَ النَّبِيُّ ﷺ يَقْسِمُ لِعَائِشَةَ يَوْمَ سَوْدَةَ»
Sauda bint Zamʿa gave up her turn to me (ʿAisha), and so the Prophet ﷺ used to give me (ʿAisha) both my day and the day of Sauda.
أَنَّ سَوْدَةَ بِنْتَ زَمْعَةَ وَهَبَتْ يَوْمَهَا لِعَائِشَةَ وَكَانَ النَّبِيُّ ﷺ يَقْسِمُ لِعَائِشَةَ بِيَوْمِهَا وَيَوْمِ سَوْدَةَ
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
Never did I find any woman more loving to me than Sauda bint Zam'a. I wished I could be exactly like her who was passionate. As she became old, she had made over her day (which she had to spend) with Messenger of Allah ﷺ to 'A'isha. She said: I have made over my day with you to 'A'isha. So Messenger of Allah ﷺ allotted two days to 'A'isha, her own day (when it was her turn) and that of Sauda. (Using translation from Muslim 1463a)
مَا رَأَيْتُ امْرَأَةً فِي مِسْلَاخِهَا مِثْلَ سَوْدَةَ بِنْتِ زَمْعَةَ مِنَ امْرَأَةٍ فِيهَا حِدَةٌ فَلَمَّا كَبِرَتْ قَالَتْ يَا رَسُولَ اللهِ «جَعَلْتُ يَوْمِي مِنْكَ لِعَائِشَةَ فَكَانَ رَسُولُ اللهِ ﷺ يَقْسِمُ لِعَائِشَةَ يَوْمَيْنِ يَوْمَهَا وَيَوْمَ سَوْدَةَ»
