Nuh (as) was trying to bring people to the right way for 950 years. Mawlana was like this also. Mawlana was bringing good tidings because we are in the end of times. Since the time of the Prophet (saws) we have been waiting for Mahdi (as) and there are many people believing they are Mahdi. But he is only one. Insha'Allah his time is near.
