14. Muhammad ibn Yahya has narrated from Muhammad ibn Ahmad from abu ‘Abd Allah, al-Jamuraniy from al-Hassan ibn Ali ibn abu Hamzah from ‘Abd Allah ibn Waddah who has narrated the following:

“Once I had a business deal with a Jewish man and he cheated me in the deal for one thousand dirham. I took him before the governor and made him take an oath, which he did. I knew that it was a sinful oath, taking on his part. Afterward a profit of many dirham emerged for him with me, I wanted to compensate the one thousand dirham from his profits; so I wrote to abu al-Hassan , about it and informed him (the Imam) about my asking the Jewish man to take oath, and that he did take an oath. That now a certain amount of profit that belongs to him exists with me; if you permit, me I can offset thereof the one thousand dirham for which he took an oath. He (the Imam) wrote back the answer, ‘No, do not take anything thereof. If he did injustice to you, you must not do injustice to him. Had you not agreed to his taking an oath, I would have commanded you to compensate from what is in your hands; but you agreed that he must take an oath and it has taken with it whatever there was? I then was stopped by the letter of abu al-Hassan .”
