Isma‘il b. Musa has said: “I heard the righteous servant (Musa) say on al-Safa (Mountain): “My Lord, (O You Who are) in the Highest Place, forgive ‘Ali b. Yaqteen!” And Imam Musa has said: “ Of the happiness of ‘Ali b. Yaqteen is that I remembered him in the Standing-place (of ‘Arafa).” These examples indicate that Imam Musa harbored love and loyalty to ‘Ali b. Yaqteen. Without doubt the Imam was sincere to him, for he was a wonderful example of piety, righteousness, and ideals.
