There is more evidence that we could discuss but what I have provided should suffice. It is clear that we cannot determine the age of Aisha with certainty as many scholars have said, but there is more evidence to point to the fact that she was between 15-18 years old when she married the Prophet ﷺ as opposed to 6 or 9 years old. We will never accurately know her age but I think we have enough evidence to suggest that she was not 6 or 9 years old when she married the Prophet ﷺ. For anyone to say that the age of 6 or 9 years old at marriage is an established fact is being disingenuous.
