abu ja'afar said: sub'HanAllah. how ignorant! ---- according to abu ja'afar, sayyidi abdul razzaq jilani was not the successor of his father in knowledge. my question is JUST WHY? what made you to exclude him from the khulafa? and what is the criteria for being a 'successor in knowledge'? imam muwaffaq al-din ibn qudama is a great hanbali imam, and a maqdisi (from the levant). how do we know that he was a khalifah? because, historians mentioned that he travelled to baghdad and stayed there and took from the ghawth. if they did not do so, it would be easier to dispute HIS being the khalifah compared to rejecting the khilafah of shaykh abd al-razzaq al-jilani. we will have a brief look at ibn qudamah, but first, we must learn about shaykh abdul razzaq. wa billahi't tawfiq.
