I've revently came across disrepectful image blaming the scholars for they way of wearing the turban. As you can see, they cites many ahadiths stating that a turban with tabiqhiyyah is the turban of Iblees (la) etc. So I would like to know why the majority of our 'ulemas wear the turban in this way? Even if these narrations were to be proven weak by their isnad, is it not better to act upon them by precaution ? Or is there another answer.

Yes they are weak, and for centuries the ulema have worn the turban like now. The ulema are very careful and would not have acted this way if there was a shubha (an issue or suspicion)
