Sayyidatuna Aisha bint Abu Bakr رضي الله عنهما was 6 years old when the prophet صلي الله عليه وسلم married her and he consummated her marriage when she was 9. This is an indisputable fact that no one has disagreed with.
Hafid Ibn Kathir said in his Serah Al Nabawiyah:
وقوله : « تزوجها وهى ابنة ست سنين ، وبنى بها وهى ابنة تسع » مالا خلاف فيه
بين الناس ، وقد ثبت في الصحاح وغيره
And his saying: (He wedded her when she was 6 years old, and consummated her marriage when she was 9 years old) there is no difference of opinion between the people about it.”
