7-71 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Yaqoob ibn Yazid, on the authority of some friends,

“I went to see Ali ibn al-Hassan Al-Askari (MGB) on a Wednesday while he was having phlebotomy performed. I told him, ‘The residents of the two Harams (implying Mecca and Medina) narrate on the authority of God’s Prophet (MGB) that whoever has phlebotomy done on Wednesdays shall suffer from white pigments and has no one but himself to blame.’ The Imam (MGB) replied, ‘No, they lie. This could only happen to those whose mothers got pregnant with them when they were menstruating.’”
