but let me ask u one thing … have u tried to read the preface of the books of history to know that what is the approch of the writer to compile the books.
if u havent than first read the disclaimer of tibri he has mentioned in the book and that how he has compiled that book. (he was king of copy pasting , whatever he gets from the public he included in his book without assessing the reasonability of the statement )
by the way havent u seen in favour or praise of yazid ibn muavia in the books of history. coz i have seen many such frm those books.
