Seems like it’s about as disputed as the Rebekah one

Hishām ibn ʿUrwa was the only one to narrate the ḥadīth, 13 and he narrated it when he was in Iraq, a time when he was accused of having a bad memory.

Asmaʾ, the older sister of ʿĀʾisha, was ten years older than ʿĀʾisha. Since Asmaʾ passed away in 73 AH/692 CE at the age of 100, this places ʿĀʾisha at eighteen years old when the marriage was consummated.

Fāṭima was born at the time the Kaʿba was rebuilt, when the Prophet ﷺ was thirty-five years old, and she was five years older than ʿĀʾisha, making Āʾisha around twelve years old when she married the Prophet.

ʿĀʾisha participated in the Battle of ʾUḥud. Ibn ʿUmar narrates that the Prophet did not permit him to participate in Uḥud because he was fourteen, but when he was fifteen the Prophet gave him permission to fight in the battle of the Trench (Khandaq). Thus, ʿĀʾisha must have been at least fifteen at the time of ʾUḥud, meaning she consummated the marriage at thirteen or fourteen years old.

ʿĀʾisha narrated in Bukhārī: “This revelation [in Sūra al-Qamar]: ‘Nay, but the Hour is their appointed time (for their full recompense), and the Hour will be more grievous and most bitter’ 14 was revealed to Muḥammad in Makkah while I was a playful jāriya.”
