Hadith: The Messenger of Allah (may Allah's peace and blessings be upon him) did not give preference to one of us over the other in terms of his division of the time he spent with us. Every day, except rarely, he used to visit all of us. He would come near each of his wives without having sexual intercourse with her, until he would reach the one whose turn was on that day and he would, thus, stay with her overnight

عن عروة قال: قالت عائشة رضي الله عنها : «يا ابن أختي كان رسول الله صلى الله عليه وسلم لا يُفضِّل بعضنا على بعض في القَسْم، مِنْ مُكْثِه عندنا، وكان قَلَّ يومٌ إلا وهو يَطُوف عليْنا جميعًا، فَيَدْنُو مِنْ كلِّ امرأة مِنْ غَيْر مَسِيسٍ، حتى يَبْلُغ إلى التي هو يومُها فَيَبِيتُ عندها» ولقد قالت سَوْدة بنت زَمْعَة: حِينَ أسَنَّتْ وفَرِقَتْ أنْ يُفارِقَها رسول الله صلى الله عليه وسلم : يا رسول الله، يَوْمِي لعائشة، فَقَبِل ذلك رسول الله صلى الله عليه وسلم منها، قالت: نَقول في ذلك أَنْزَل الله تعالى وفي أَشْبَاهِها أُراه قال: {وإن امرأة خافت من بعلها نشوزًا} [النساء: 128].

‘Urwah reported: ‘Ā'ishah (may Allah be pleased with her) said: "O my nephew, the Messenger of Allah (may Allah's peace and blessings be upon him) did not give preference to one of us over the other in terms of his division of the time he spent with us. Every day, except rarely, he used to visit all of us. He would come near each of his wives without having sexual intercourse with her, until he would reach the one whose turn was on that day and he would, thus, stay with her overnight. When Sawdah bint Zam‘ah became old and feared that the Messenger of Allah (may Allah's peace and blessings be upon him) might divorce her, she said: 'O Messenger of Allah, I give my day to ‘Ā’ishah.' The Messenger of Allah (may Allah's peace and blessings be upon him) accepted it from her. We believe that Allah, the Exalted, revealed about this incident or similar ones the verse: {If a wife fears cruelty or desertion on her husband's part...} [Sūrat An-Nisā':128]"
[Good hadith] - [Narrated by Abu Daoud - Narrated by Ahmad]

Explanation

This Hadīth highlights the justice of the Prophet (may Allah's peace and blessings be upon him) in dividing the nights among his wives. He did not favor anyone over the other. ‘Ā'ishah (may Allah be pleased with her) mentioned that the Prophet (may Allah's peace and blessings be upon him) used to pass by his wives every night, and he would fondle his wives and spend some intimate time with them without having sexual intercourse. He did that to comfort them, and out of maintaining good companionship with them. He used to spend the night at the house of the one whose turn was up. When Sawdah bint Zam‘ah grew older, she became worried that the Prophet (may Allah's peace and blessings be upon him) might leave her, but she wanted to stay as his wife and keep that honor, being a Mother of the Believers and one of the wives of the Prophet (may Allah's peace and blessings be upon him). Therefore, she decided to give up her day to ‘Ā'ishah, and the Prophet (may Allah's peace and blessings be upon him) accepted that from her. Then, ‘Ā'ishah (may Allah be pleased with her) mentioned that the verse: {If a wife fears cruelty or desertion on her husband's part…} [Sūrat An-Nisā': 128] was revealed concerning this situation and others like it.
