P10.0 Breaking One’s Fast During Ramadan
p10.1 The Prophet (Allah bless him and give him peace) said:
(1) “Whoever breaks a fast-day of Ramadan without an excuse or dispensation could not requite it by fasting a lifetime, were he to do so [A: meaning that making up that day, while obligatory, does not remove the sin, though repentance does].”
The above hadith is not well authenticated.
(2) “The five prescribed prayers, and from one Friday prayer to another or from Ramadan to Ramadan, expiate the sins between them as long as the enormities are avoided.”
(3) “Islam is based on five things: testifying that there is no god but Allah and that Muhammad is the Messenger of Allah, performing the prayer, giving zakat, fasting Ramadan, and the pilgrimage to the House (Kaaba).”
