15. My father (rah) said: it was narrated to me by Sa’d b. Abdillah who said it was narrated to me by Ibrahim b. Hashim from ’Amru b. Uthman from Ahmad b. Ismail al-Katib who said: It is narrated that one of the groups of Quraish saw Imam Muhammad bin Ali  in Masjidul Haraam and began to say: ‘The people of Iraq worship him.’ One of them advised that they send a person to him to ask a few questions. A person came to Imam and asked, “O uncle! What is the greatest sin?” Imam  replied, “Drinking wine.” He went to his people and told him about the Imam’s reply. They told him to go and ask the same question again. The person came to the Imam and repeated the question. Imam  answered, “O nephew! Didn’t I reply you last time? Drinking wine forces a person to commit adultery, theft, murder and polytheism. The effects of wine are more than any other sin just like its tree is taller than other trees.”
