“One of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, has said, ’If a man performs al-Hajj along with his small son, he must instruct him to say Talbiyah and make al-Hajj obligatory. If he cannot say Talbiyah correctly, he (the father) must say it on his behalf, make him to perform Tawaf and perform Salat (prayer) on his behalf.’ I then asked, are they not required to offer al-Hady (sacrifice)?’ He (the Imam) said, ’Sacrifice is required for small ones and fast is required from grown up people, and they must stay away in the state of Ihram from whatever the grown up people must stay away, and if he kills a prey his father must pay the expiation.’”
