Chapter on Sunnahs of Fasting

And from him, from Muhammad ibn Abi Umayr, from Hammad ibn Uthman, from Muhammad ibn Muslim, who said: Abu Abdillah عليه السلام, peace be upon him, said: “When you fast, then let your hearing, your sight, your hair, and your skin fast.” And the Imam عليه السلام enumerated things other than this. Imam عليه السلام said: “And the day of your fasting should not be like the day of your breaking the fast.”
