“I once said to abu Ja‘far (a.s.), ‘A Hadith has reached me from al-Hassan al-Basriy. If it is a true Hadith then, ‘We are for Allah and to Him we return.’ He (the Imam) asked, ‘What does it say?’ ‘I am told that al-Hassan al-Basriy would say that even if his brain comes to a boiling point due to the hot sun, he will not seek shelter of the shadow of a wall that belongs to a money changer. Even if his liver cracks down because of thirst he will not use the water that comes from the house of a money changer.’ This is my business and profession. With this business my flesh and blood have grown. With this business I have performed Hajj and ‘Umrah.’ He (the Imam) sat straight and said, ‘Al-Hassan has spoken a lie. Take with fairness and give with fairness. When it is time for Salat (prayer), stop doing business and rise for Salat (prayer). Did you know that people of the cave were Say ar if ah (money exchangers)?”’
