Abu Ja`far Muhammad b. `Ali b. al-Husayn b. Musa b. Babuwayh al-Faqih al-Qummi (ra) narrated to us. He said: My father (rh) narrated to us. He said: Sa`d b. `Abdullah narrated to us from Ahmad b. al-Husayn from Muhammad b. Jamhur, and from Muhammad b. Ziyad from one who heard Muhammad b. Muslim al-Thaqafi say: I heard Abu Ja`far Muhammad b. `Ali al-Baqir (as) say: For Allah, there are angels assigned to those who fast. They seek repentance for them every day in the month of Ramadan until its end. They call to those who fast every night at the time of their breakfast: “Rejoice, servants of Allah, for you have hungered little and will be satiated much. You will be blessed, and blessing will come by you” – until the end of the night in the month of Ramadan, wherein they will call to them: “Rejoice, servants of Allah, for Allah has forgiven your sins and accepted your repentance. So, see how you will be when you continue.”
