9. Ali ibn Muhammad has narrated from Ahmad ibn Muhammad ibn Khalid from al-Washsha’ from Ali ibn abu Hamzah from abu Basir who has said the following: “I heard abu ‘Abd Allah عليه السلام, say, ‘Fasting is not abstaining from food and drink only. Mary had said, “I have made a vow before the Beneficent to fast,” meaning thereby to remain silent. You must control your tongues and cast down your eyes. You must not be jealous and you must not quarrel. Jealousy consumes belief just as fire consumes fire wood.’”
