It was almost certain that Sallu Bhai will be seen in the film but his separation from the project made everyone curious to know the reason behind Salman not being in Shuddhi.
Several speculations are being made and different reasons are being rumoured for Salman parting ways with Karan Johar's Shuddhi.
One of the supposed reasons for Salman backing out from Karan Johar's ambitious project is relating to date issues. Apparently, Karan wanted Salman Khan to allot as many as 180 days for Shuddhi which the actor was not very comfortable with. As reported, Salman opined that he can do three films in these many days and so he opted out of the project.
On the other hand, another reason behind Salman not being in Shuddhi is supposed to be jokes on Arpita Khan (Salman's sister) in the controversial AIB Roast, of which Karan Johar was a part.
Although, none of the supposed reasons are confirmed, one thing is certain that the decision was an amicable one.
