7-67 Muhammad ibn al-Hassan - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Muhammad ibn Ahmad ibn Yahya ibn Imran al-Ash’ari, on the authority of Al-Abbas ibn Ma’ruf, on the authority of Muhammad ibn Abi Umayr, on the authority of Abi Hamzih, on the authority of Aqabah ibn Bashir al-Azodi,

“I went to see Abi Ja’far al-Baqir (MGB) on a Monday. He (MGB) said, ‘Have something to eat.’ I replied, ‘I am fasting.’ The Imam (MGB) said, ‘Why did you fast on this day?’ I said, ‘Because the Prophet (MGB) was born on this day.’ He (MGB) said, ‘You do not know on which day the Prophet (MGB) was born on. That is the day on which the Prophet (MGB) perished. Therefore, you should neither travel nor fast on that day.’”
