I'm confused whether the age of Ibn Abbas (May Allah be pleased on him) was 8 or 13 at time of the death of Muhammad (SAW).
I've read a book which says, it is 8. But in different websites, it says, 13. In Wikipedia, they have failed to provide any references to support "13". However, even if they give, I don't care. Their references are not always reliable.
In other website, they have also failed to provide references to support "13".
So plz answer with references from the books of the reliable and renowned scholars so that they can be cited as reference or from such type website for example: Islamqa. I mean, I want a reliable references. Not from any website. That's why, I would be thankful if anyone give references from the books of scholars.
