Fasting According To the Five Schools of Islamic Law

Obligatory fasts

All the schools concur that the wajih fasts are those of the month of Ramadan, their qada', the expiatory fasts performed as kaffarah, and those performed for fulfilling a vow. The Imamis add further two, related to the Hajj and solitude in masjid (i`tikaf). We have already dealt in some detail with the fast of Ramadan, its conditions and the things that invalidate it. Here we intend to discuss its qada' and the kaffarah to which one who breaks it becomes liable. Other types of obligatory fasts have been discussed under the related chapters.
