abu taalib

Did Abu Talib accept Islam?

Q: Why is there a lot of ikhtilaaf on the Imaan of Hazrat Abu Talib? Some say he is Kafir, some say Sahaabi and some say to keep queit about Hazrat Abu Talib?

My Question is that if a person like me who does not have much knowladge about Islam, by talking about Hazrat Abu Talib, will my Iman be snatched away? Is this a part of basic Aqeeda or Belief? Please Explain?
