What things are bad in Islam?

[WinterHold]

Where did people get the idea that Aisha was 9 from?

The story goes :

With the prophet, there were writers, called (the writers of the revelations). When the prophet gets a revelation, they directly write it. The oldest and most trusted source is this (aka, Quran).

After 200 years from the prophet's death, some scholars wanted to document what he said, other than the revelations.

there books came to be known as (the hadith books). They are written on asking people about what they heard, other than the quran.

that's the source of aisha being 9.

so, we can clearly say : the prediction of aisha's age came after 200 years, which makes it "very untrusted".

BTW, most problems in islam are caused by these books, and their contradictions.
