This fatwa or alert is a face saving message. Don't read too much into it. No body including the signatories doesn't believe in it from the core of their heart.
Ask any person from Hyderabad and he'll tell you about the precedents of this guy, Madani who is an 'honourable' MP and looks like an influential memeber of the body that issued Fatwa.
Probably one of the most notorious criminals who sits in the Parliament today is this guy. And here he's talking peace. Tch Tch!!!
