“Once I was walking with abu al-Hassan (a.s.) on a certain side of the city of Madina. He joined his legs on one side of the animal he was riding, dismounted and went to prostrate on the ground. He prolonged and prolonged the prostration. He then raised his head and mounted the animal. I then said, ‘May Allah keep my soul in service for your cause, you had a very long prostration.’ The Imam said, ‘1 just remembered a favor that Allah had granted me and I loved for it to thank my Lord.’”
