'I visited Abu al-Hasan al-Rida (AS) when he was in Makkah. I saw him peel a banana and feed it to Abu Ja'far. I asked him, may I be your ransom, is this the blessed newborn?' He said, 'Yes, O Yahya! This is the newborn the like of whom there is none other born into Islam and upon our shi'a, more blessed than him.'
