It was narrated that Ibn 'Abbas said: "When the Messenger of Allah died he had nine wives; he used to be intimate with all of them except one, who had given her day and night to 'Aishah."
تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَعِنْدَهُ تِسْعُ نِسْوَةٍ يُصِيبُهُنَّ إِلاَّ سَوْدَةَ فَإِنَّهَا وَهَبَتْ يَوْمَهَا وَلَيْلَتَهَا لِعَائِشَةَ
