Muslims, do you believe that Prophet Mohammad will intercede for you on Judgment day...?

this is a complicated question. Sadly many Muslims today dont even know what Islam is. If you do Shirk you are automatically out of the folds of Islam and all good deeds that person did are nullified. If you die upon this without repenting you die a kaffir. So how can you expect out prophet to intercede for that person. The prophet will be there enemies on that day and people dont even realise this. we have to constantly ask for forgiveness and guidance from allah.
