Imam Musa, peace be on him, showed loyal affection and friendship for ‘Ali. For example, he visited him one day and said to his companions:
-If one is happy to see one of the companions of Allah’s Apostle, may Allah bless him and his family, than let him look at that coming (man)-he indicated with his hand to ‘Ali.
One of those present asked him:
-Is ‘Ali among the people of the Garden?
-As for me, I bear witness that he is of the people of the Garden.
‘Ali sent a person to Imam Musa to ask him to invoke Allah for him. When the person was in front of the Imam, peace be on him, he said to him:
-O Son of Allah’s Apostle, ‘Ali b. Yaqteen has sent me, that you may invoke Allah for him.
-For the hereafter?
-I have guaranteed that the fire will never touch ‘Ali!
