Sunan Ibn Majah, Volume 3, Book 9, Hadith 1971 (DarusSalam) ⓘ
It was narrated that 'Aishah said: "The Messenger of Allah used to divide his time equally among his wives, then he would say 'O Allah, this is what I am doing with regard to that which is within my control, so do not hold me accountable for that which is under Your control and is beyond my control.'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ يَحْيَى، قَالاَ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلاَبَةَ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَقْسِمُ بَيْنَ نِسَائِهِ فَيَعْدِلُ ثُمَّ يَقُولُ " اللَّهُمَّ هَذَا فِعْلِي فِيمَا أَمْلِكُ فَلاَ تَلُمْنِي فِيمَا تَمْلِكُ وَلاَ أَمْلِكُ " .
