Chapter on Reward of Fasting

And from him, from Amr ibn Uthman, from Abdullah ibn al-Mughirah, from Ismail ibn Abi Ziyad al-Shairi, from Abu Abdillah Imam Ja’far عليه السلام from his father, Imam al-Baqir عليه السلام, peace be upon them both: Imam عليه السلام said: “The Prophet صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family, said to his companions: ‘Shall I not inform you of something which, if you do it, Satan will become distant from you just as the east is distant from the west?’” They (companions) said: “Yes.” The Prophet صلى الله عليه وعلى آله وسلم said: “Fasting blackens his (Satan) face, charity breaks his (Satan) back, love for the sake of Allah سبحانه وتعالى and mutual support in righteous action cut off his (Satan) root, and seeking forgiveness cuts off his life-vein.” And the Prophet صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family, said: “For everything there is a zakat, and the zakat of the body is fasting.”
