Usool at tafseer

For people who is interested in learning on how the scholars of past and present used to follow certain way or say guidelines they followed to write tafsir then this is a great book to know the basic of it.....Knowledge of this deen is like a ocean and all the books you read will only let you get a drop of it so pls don't think we attained great knowledge by reading a single book. Keep your intentions clean and for sake of Allah and be diligent.
