ذِكْرُ الْقَدْرِ الَّذِي مَكَثَتْ فِيهِ عَائِشَةُ عِنْدَ النَّبِيِّ ﷺ
that the Prophet ﷺ married her when she was six years old and he consummated his marriage when she was nine years old, and then she remained with him for nine years (i.e., till his death). (Using translation from Bukhārī 5133)
«أَنَّ النَّبِيَّ ﷺ تَزَوَّجَهَا وَهِيَ بِنْتُ سِتٍّ وَأُدْخِلَتْ عَلَيْهِ وَهِيَ ابْنَةُ تِسْعٍ وَمَكَثَتْ عِنْدَهُ تِسْعًا»
