Wikipedia:Articles for deletion/Tahir ibn Muslim
the source is a WP:RS which is about the only modern scholar I could find to deal with this particular subject. This does not mean that this person is non-existent or non-notable; being the hereditary ruler of one of the two holiest cities in Islam is clearly notable. Rather, it is a typical example of  on the topic in Western sources. On Srnec's concerns, these are valid, but should be examined independently, to determine the 'truth' as far as we can, before any decision on keeping or deleting or renaming or merging this particular article
