Fake descendants  Having the last name of Jilani does not make someone a descendant of the Shaikh  It just signifies that someones ancestor has come from Jilan or someone was a descendant of someone named Jilani  Maybe someone became a Muslim on the hand of Jilani  There are lots of Jilanies who are Shias and dead against the Shaikh  After the  partition many people changed their family name during the crossing  Even someone is a descendant of Shaikh he can be a convert to Wahhabism  I have seen some Jilani converts to Christianity
