Testifying Imam Ali’s Imamate in Adhan for the first time by Salman the Persian
One of the companions of Prophet Muhammad (pbuh) told him: Oh messenger of God! today, I heard something for the first time.
The prophet asked: what’s that?
He said: Salman was reciting the Adhan (call to prayers). I heard that he testified (Imam) Ali’s imamate after testifying the oneness of God and Muhammad’s Prophecy.
The prophet said: you heard a good thing.
