I am least interested in such discussions where one prove with ample evidence a point and other reliance is on net. For ur kind info i consider chach nama best buk and others. And net is rich with hindus filthy and faulty argumentation and ironically there is not a single historia neither was which encounter these. Utbi was historia , u can rely on farishta because i've extracted materials 4m these books. So rely on net and have a gud paper.
