Salam alaykoum wa rahmatouLlahi wa barakatouhou,
In this time when some books are being falsified and modified to suit the interest of particular people, is there a way to verify the validity of completeness of a book when we want to buy one?
How to make sure the version of any fiqh book we want to buy is complete and hasn’t been tampered with, as for instance some ahadiths have been removed from Sahih Boukhari and we may end up with an incomplete edition?
Usually it becomes common knowledge if an edition is sound or unsound. Therefore ask around on a specific basis and in sha Allah you will be able to avoid bad editions. As for Sahih al-Bukhari the available editions past and present are complete and uncut to our knowledge.
