6. A number of our people have narrated from Sahl ibn Ziyad from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘Once there was a group of people with my father and they had different views about al-Nabidh. Certain ones among them said, “The cupful (of al-Nabidh) which is intoxicating is unlawful.” Others said, “Al-Nabidh in small quantity does not intoxicate but it is unlawful in large quantity.” They referred the matter to my father (a.s.), who said, “On the basis of fairness and justice if nothing has been placed in the cup it would never become full. This applies to the other cup also. If nothing has been placed in, it would not intoxicate.” He (the Imam) said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘If a small quantity of that which in large quantity intoxicates, enters one’s vein, Allah will make that vein suffer because of three hundred sixty kinds of torments.”””
