Hadith 10:50
‘A’isha said that the Prophet married her when she was seven, she was brought to live with him when she was nine bringing her toys with her, and he died when she was eighteen. Muslim transmitted it.
وَعَنْ عَائِشَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ تَزَوَّجَهَا وَهِيَ بِنْتُ سَبْعِ سِنِينَ وَزُفَّتْ إِلَيْهِ وَهِيَ بِنْتُ تِسْعِ سِنِينَ وَلُعَبُهَا مَعَهَا وَمَاتَ عَنْهَا وَهِيَ بِنْتُ ثَمَانِيَ عَشْرَةَ. رَوَاهُ مُسلم
