Sayyiduna Abu Musa Ash’ari (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty will gather all the nations on a barren plain on the Day of Resurrection. When Allah wills to judge between His creation, He will present before every nation the form of whatever they used to worship. Those people will follow their respective deities and enter Hell, while we will be on a high place. Our Lord will come to us and say: Who are you people? We will reply: We are Muslims. He will ask: Whom are you waiting for? We will say: We are waiting for our Lord. He will ask: Will you recognize Him when you see Him? We will say: Yes. He will ask: But you have never seen Him, so how will you recognize Him? We will say: We will recognize Him because He is unique; there is none like Him. Then Allah Almighty will appear before them smiling and say: O Muslims! Congratulations, for I have sent a Jew or a Christian to Hell in place of each one of you.
