Narrated 'Urwah (RA):

'Aishah (RA) said: "O my nephew, Allah's Messenger (ﷺ) would not prefer some of us over others regarding the division of the time he would spend with us. It was very rare that he would not visit us all, and come near each of his wives without having intercourse with her, till he reached the one whose day it was, and spent the night with her." [Reported by Ahmad and Abu Dawud, the wording is Abu Dawud's. al-Hakim graded it Sahih (authentic)].

وَعَنْ عُرْوَةَ قَالَ : { قَالَتْ عَائِشَةُ : يَا اِبْنَ أُخْتِي ! كَانَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-لَا يُفَضِّلُ بَعْضَنَا عَلَى بَعْضٍ فِي اَلْقَسْمِ مِنْ مُكْثِهِ عِنْدَنَا , وَكَانَ قَلَّ يَوْمٌ إِلَّا وَهُوَ يَطُوفُ عَلَيْنَا جَمِيعًا , فَيَدْنُو مِنْ كُلِّ اِمْرَأَةٍ مِنْ غَيْرِ مَسِيسٍ , حَتَّى يَبْلُغَ اَلَّتِي هُوَ يَوْمُهَا , فَيَبِيتَ عِنْدَهَا } رَوَاهُ أَحْمَدُ , وَأَبُو دَاوُدَ وَاللَّفْظُ لَهُ , وَصَحَّحَهُ اَلْحَاكِم ُ [1]‏ .‏
