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»
