Musannaf Ibn Abi Shaybah 9125 — The fasting person being commanded

Sayyiduna Jabir (may Allah be pleased with him) said: When one of you is fasting, his ears, his eyes and his tongue should also fast from lying and sin. He should refrain from harming his servant. On the day of his fast, dignity and tranquillity should prevail over him. He should not make the day he fasts and the day he does not fast alike.
