Islam Critiqued the defamer; hafs was a liar?

In answer to the video "Miraculous Preservation of the Quran: Burying the Myth"

Although Hafs was rejected as a hadith narrator, a science that is completely unrelated to the art of Quran recitation or capacity to memorize, he was however never questioned in the field of recitation itself, neither by those who deemed him untrustworthy in hadith nor by his fellow students. As to the fact that Hafs would borrow books to copy them without returning them, with the only specific case mentionned being a book from his contemporary student colleague Shu'bah, what is important to mention firstly is that only Shu'bah made that claim, which is why no other explicit example of borrowing and not returning exists.

Second, it was nothing strange and in fact the norm back then for even powerful narrators to borrow eachothers' books and copy the narrations they contained into their hadith collection. As to not returning Shu'bah's book, this could have been due to many things other than "stealing". Nobody ever accused Hafs in that context of being a book thief!
