15. A number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from abu Hamzah al-Thumaliy who has said the following: “I once asked abu Ja‘far , about a slave if there is expiation for al-Zihar on him. He (the Imam) said, ‘He owes one-half of what is due on a free person of fasting, and setting free of slaves as expiation does not apply in his case as well as paying charity.’”
