1. Al-Husayn ibn Muhammad has narrated from Mu‘alla’ ibn Muhammad from af-Washsha’ from Hammad ibn ‘Uthman who has said the following: “I heard abu ‘ Abd Allah , say, ‘The Messenger of Allah continued fasting for such a long time that people thought he would not discontinue it. He then discontinued fasting for such a long time that people thought he would not fast. Then he began fasting as Dawud , did. One day he would fast and not fast the next day. He left this world with a practice of fasting three days every month. The Imam said, ‘Fasting three days every month is like fasting a whole month. This removes wahr from one’s chest. Wahr means temptation.’ Hammad has said, ‘I then asked, which days are they?’ He (the Imam) replied, ‘Every first Thursday, every first Wednesday after the tenth of the month and the last Thursday therein.’ I then asked, ‘How did these days become as such?’ He replied, ‘The days when torment descended on the people of the past were one of these days. Because of fear, the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, would fast during these days.’”
