Imam Jafar Sadiq (a.s.) informed – On the Day of Judgement, a caller will call from the side of the Throne, “Where is Allah’s Caliph on His land?” Then Prophet Dawood will stand up.

Allah will say, “We did not mean you, even though you are a caliph.”

Then he (the caller) will call again, “Where is Allah’s Caliph on His land?”

Then Ameerul Momineen (a.s.) will rise.

Allah will say, “O creatures! This is Ali bin Abi Talib, Allah’s Caliph on His land and His decisive argument on His slaves. So those of you who held on to him in life, hold on to him now. See with his light and follow him to the highest levels of Paradise.”

So a group of people who followed Ali (a.s) In life will stand up and follow him to Paradise.

Then Allah will say, “Whoever followed someone else In their life, follow them today wherever they go.”

Then Allah will say: When those who were followed shall renounce those who followed them, and they see the punishment, and their ties are cut asunder; and those who followed shall say, ‘Had there been for us a return. Then we would renounce them as they renounced us.’ Thus Allah will show their deeds to be (the cause of) intense regret to them, and they shall not come forth from the fire (Surah Baqarah (2):166-167)
