"The Messenger of Allah used to divide his time equally among his wives then he would say: 'O Allah, this is what I have done with regard to that over which I have control, so do not blame me for that over which You have control and I do not.'" Hammad bin Zaid narrated it in Mursal form.
كَانَ رَسُولُ اللَّهِ ﷺ يَقْسِمُ بَيْنَ نِسَائِهِ ثُمَّ يَعْدِلُ ثُمَّ يَقُولُ اللَّهُمَّ هَذَا فِعْلِي فِيمَا أَمْلِكُ فَلاَ تَلُمْنِي فِيمَا تَمْلِكُ وَلاَ أَمْلِكُ أَرْسَلَهُ حَمَّادُ بْنُ زَيْدٍ
