“Once I said to al-Rida (a.s.), before Allah’s granting you the blessing of the birth of abu Ja’far (a.s.) we would ask you and you would say, “Allah will grant me a son and He has granted you one. His birth is the delight of our eyes. May Allah spare us from showing your (sad) day. However, if something will happen to who then (will leadership with Divine Authority) will go?” The Imam (a.s.) pointed out with his hand towards abu Ja’far (a.s.) and he was standing before him. I then asked, “ May Allah take my soul in service for your cause, a child of three years?” The Imam (a.s.) said, “That will be of no harm to him. Jesus rose with Divine authority when he was a three years old child.”
