tahir never claimed to have sat in a classroom. he claims that he was personally tutored by Imam e Azam, and As-Suyuti, for roughly 20 years, and that he routinely receives abundant spiritual blessings from Ghawth e Azam - all in his dreams. i don't know what daleels he presented to Imam e Azam in his dream when he disagreed with him on the diyat issue. he hasn't shared them with the rest of the world either! i don't know if gibril too has such fantastic dreams of Imam Shafi3i teaching him to fall back on, but dreams have already started to be narrated on eshaykh about people seeing nazim.
