“I once said to abu Ja‘far, the second ‘Alayhi al-Salam, ‘I want to perform Tawaf on your behalf and on behalf of your father.’ It was said to me, ‘Tawaf is not performed on behalf of the executors of the will (of the Messenger of Allah).’ He (the Imam) then said, ‘Perform Tawaf as much as you can; it is permissible.’ I then after three years said, to him, ‘I had sought permission from you to perform Tawaf on your behalf and on behalf of your father and you had granted permission. I then performed Tawaf on behalf of both of you as much as Allah willed. I then said, ‘Then something came to my mind and I then did something accordingly.’ He (the Imam) asked, ‘What did you do?’ I then replied, ‘I one day performed Tawaf on behalf of the Messenger of Allah; he (the Imam) said three times, “O Allah, grant salawat (favors and compensation to Muhammad worthy of his services to your cause).” I then on the second day performed Tawaf on behalf of ’Amir al-Mu’minin. On the third day, I performed Tawaf on behalf of al-Hassan (a.s.). On the fourth day, I performed Tawaf on behalf of al-Husayn (a.s.). On the fifth day, I performed Tawaf on behalf of Ali ibn al- Husayn. On the sixth day, I performed Tawaf on behalf of abu Ja’far; on the seventh day, I performed Tawaf on behalf of Ja’far ibn Muhammad. On the eighth day, I performed Tawaf on behalf of your grandfather, Musa ibn Ja’far. On the ninth day, I performed Tawaf on behalf of your father. On the tenth day, I performed Tawaf on your behalf, O my master. These are those whose divine authority is part of my religion in obedience to Allah.’ He (the Imam) said, ‘The religion you have followed in obedience to Allah is the one beside which no other religion is accepted from the servants (of Allah).’ I then said, ‘I may have performed Tawaf on behalf of your mother, Fatimah, ‘Alayha al-Salam, also, or may not have done so.’ He (the Imam) said, ‘You should do so very often; this is better than what you may do, by the will of Allah.’”
