You are exactly true Shri Yadav and also a good HINDU. If few foolish people are worshipping dargah and incidently happen to be HINDUS, dont equate whole HINDU religion visits dargah. Because of some fools like manu HINDUS are considered to be cowards.Tell your muslim friend that RAM and rahim is one, all religion are equal, and then see what is his reply to you. What is the capacity of the total dargahs around, how much hindus visit dargahs, rediff make a survey. And then tell that it is worshipped by hindus if the percent is more than fifty.
