30-38 Muhammad ibn Musa ibn al-Mutawakkil - may God be pleased with him - narrated that Ali ibn Ibrahim ibn Hashem quoted on the authority of Ishaq ibn Ibrahim, on the authority of Moqatil ibn Moqatil, “I saw Abul Hassan Al-Ridha on a Friday at noon while he was in the state of ritual consecration for the Hajj (or wearing ‘Ihram) and performing a phlebotomy at the roadside.”The author of this book (Sheikh Sadooq) - may God have Mercy upon him - said, “There are several conclusions we can draw from this tradition. At first it shows us that performing a phlebotomy on Fridays is fine when needed. What has been stated about its being admonished against apply to when it is not really necessary to do so. The second conclusion we can draw is that a blood-letting can be performed at noon. The third conclusion is that if one is in the state of ritual consecration for the Hajj, he can perform a phlebotomy if needed, but he should not shave the hair in the place where he wants to perform the phlebotomy.”
