Age Of Aisha R.a.
As Ghamidi sahab stated that this is history, not a matter of religion. Even that history was written after roughly 200 years, so there’s definitely room for error. He has raised some very valid questions that no rational mind can ignore. Other than that, no one can really establish the truth beyond any reasonable doubt.
Multiple accounts doesn’t make anything certain – they still remain ahaad narrations. Also it doesn’t raise any doubts on questions regardless of when they surfaced up. As in every field of knowledge, most of the time people only critically analyze anything when they find a need to do so.
Regarding the tradition of Hazrat Aisha’s marriage and consummation at a young age, there are several aspects worth considering: After the death of Hazrat Khadija, the proposal for this marriage was made to provide companionship and to fulfill domestic responsibilities. It is unreasonable to expect a six-year-old child to handle these responsibilities. One perspective is that since the calendar was established much later, during the caliphate of Hazrat Umar, ages before this time were estimated. Hazrat Aisha might have reported her age at the time of marriage and consummation as an approximation, which could account for a few years’ difference. Similarly, there is the matter of her age at the time of her death, which historians claim was 66 years in the year 58 Hijri. Subtracting 58 from 66 results in an age of 8 years at the time of migration. However, it is not necessary that her actual age was precisely 66; a few years’ difference is also possible.
