Question: If a Muslim does not fast for two consecutive days during Ramadhaan due to a [Islaamically] valid reason, then how should he make them up?
Response: He is required to make them [both] up – even if he splits them [up]. [However], he is not required to fast [any of the missed days of] Ramadhaan consecutively, because Allaah (Subhaanahu wa Ta’aala) said:
{…and whoever is ill or on a journey – then an equal number of other days…}, soorah al-Baqarah, aayah 185
[And] He did not say [they are to be made up] consecutively.
[So] if he did not fast for two days, or three or more, then he must make them [all] up, and he is not required to [do so] consecutively. If, [however], he [does] fast [them all] consecutively, then that is best, and if he does not [do so], then there is no harm [in that].
