The majority further require that the three days of fasting be consecutive, following the reading of ʿAbd Allah ibn Masʿūd: “then fasting three consecutive days.”
Many ordinary people err at this point: they imagine that fasting is an equal alternative to the other forms of expiation, so they fast even though they are able to feed or clothe the poor.
