Giving one‘s young children in marriage

Narrated 'Aisha:

that the Prophet 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).

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ

أَنَّ النَّبِيَّ ﷺ تَزَوَّجَهَا وَهْىَ بِنْتُ سِتِّ سِنِينَ، وَأُدْخِلَتْ عَلَيْهِ وَهْىَ بِنْتُ تِسْعٍ، وَمَكَثَتْ عِنْدَهُ تِسْعًا.
