The Messenger of Allah said to Ali :
O Ali, on the Day of Judgement, you will be brought sitting on a pulpit of light. There will be a crown on your head that shines so brightly that it will almost blind people.
Allah will call out, Where is the successor of Mohammad, the Messenger of Allah?
Then, O Ali, you will say, Here I am.
Then the caller will say, Those who loved you, let them enter Paradise, and those who were against you, send them to Hell.
Therefore, you (Ali ) will divide those who go to Paradise and those who go to Hell, and this is an order from the All-Powerful King.
