Walaykum salam. They are very worried, indeed. Before each and every one of our ijtemaat, they take pledges at street corners and in the slums where they are centred that the Barelwis will not go to attend the Ijtema. Its "Shock and Awe" for al Barelwiyyah. I don't know who their "senior scholars" are because their definition of a scholar is someone dressed in a flourescent green, yellow or saffron robe accompanied by two cabbages on his head which he ties with a huge brown turban, shrieks and shouts on the stage, abuses the people of Tawhid & Sunna roundly, collects his money for his "act", eats like a glutton and sleeps like Kumbhakaran while Fajr is going on. So you might have some difficulty in searching for a "scholar" in them. They might want to bring it up with Sayyidi Habib 'Ali because they have started suspecting his Sunnism because of his support for the work of Da'wah. WS.
