The prescribed book for the course is Subulus-Salaam by the 17th century Yemenite scholar Muhammad ibn Ismaa‘eel as-San‘aanee which is a commentary on Buloogh al-Maraam written by Haafiz Ibn Hajar al- ‘Asqalaanee. In Buloogh the author gathered the majority of the hadeeths which are commonly used as the basic evidences for the Islamic legal system. The course material is comprised of the Chapter on Fasting (Kitaab as-Siyaam) from Subulus-Salaam.
We Muslims fast the month of Ramadaan because Allaah has commanded us to do so. Allaah says (interpretation of the meaning): “ O you who believe! Observing As-Sawm (the fasting) is prescribed for you as it was prescribed for those before you, that you may become Al-Muttaqoon (pious)” [al-Baqarah 2:183]
