I heard Al-Ridha (s) narrate on the authority of his father, on the authority of his forefathers, on the authority of Ali (s), ‘God’s Prophet (s) performed a phlebotomy even when he was fasting and in the state of ritual consecration for the Hajj.’”The author of this book (Sheikh Sadooq) - may God have Mercy upon him - said, “This tradition is not in contradiction with another tradition quoted on the authority of God’s Prophet (s) which says, ‘Aftar al-Hajim val Mahjoom’ which implies that both those who fast and perform a phlebotomy have entered into my tradition and my nature.”
