ANSWER:

This is not true! People of the book who had heard of the Prophet salla Allahu alaihi wa sallam yet still refused to accept Islam will stay in hell for eternity and will never enter Paradise. 

someone told me that the people of the book will eventually enter paradise. Then the question comes then why pray and so on people can just do anything they want too. I think this understanding is incorrect and I think it falls under one of the category of nullifying Islam. This I think came from someone in the family who is ignorant in Islamic understanding and is spreading this. What should I tell this person, I am not knowledgeable in this subject please tell me what to do?
