ghouse paak

Q: Who is ghous-e-aazam. I want to know about him.

Q: My question is regarding khatams and niaz etc in the name of the Prophet Salallahu-Alaihi-Wasalam and saints like Hazrath Ghous Paak etc - Is this practise Islamically correct or is it considered bidaah?

Q: I would like to know the tablighi jamaats view of ghouse paak. Apparently this is his month were he passed away and the sunnis will be having a "big night". I know of people who take vows in his name and other things. I have read that he could perform miracles. Is this true?
