in reply to Safwan al-Jammal asking about one who holds this position [of Imama], said, 'One who holds this position does not play and nor is he distracted.' Musa b. Ja'far, who was then a child entered accompanied by a Makkan she-goat, to whom he was saying, 'Prostrate to your Lord!' So Abu 'Abdillah took him and hugged him and said, may my parents be your ransom, he never plays and nor is he distracted.'
