1604. If a person who is fasting intentionally ascribes a false statement to God, the prophet (Peace be upon him and his progeny) or the Infallible Imams (Peace be upon them all), be it in writing, verbally or by mere gestures, his fast will be rendered void, even if he immediately confesses to lying or repents for his act. As for ascribing a lie to the rest of the prophets and their successors (may peace be upon our prophet, his progeny and upon them), it will also render the fast void based on obligatory precaution, unless the ascription reverts to God the Exalted, in which case his fast is invalid. The same will apply to ascribing false statements to Lady FÁÔimah ZahrÁ‘ (Peace be upon her), unless the ascription reverts to God the Exalted, or the prophet (Peace be upon him and his progeny (, or the Imams (Peace be upon them all), in which case the fast is invalid.
1605. If a person wishes to narrate a statement that he does not know to be true or false, and neither does he possess any evidence for its authenticity, obligatory precaution dictates that he should narrate it from the person who stated it, or for example, from the book in which the statement was written.
1606. If a person ascribes a statement to God, the prophet (Peace be upon him and his progeny) or one of the Imams (Peace be upon them all), believing it to be true, but later finds out that it was false, his fast will not be invalidated.
1607. If a person knows that ascribing a lie to God, the prophet (Peace be upon him and his progeny) or one of the Imams (Peace be upon them all) invalidates the fast, and goes on to ascribe a lie to them, but realizes later on that the statement was in fact true, his fast will be invalidated nonetheless. Obligatory precaution dictates that he should refrain from committing all the acts which invalidate a fast for the rest of the day.
1608. If a person deliberately ascribes a lie which was concocted by another person to God, the prophet (Peace be upon him and his progeny) or one of the Imams (Peace be upon them all), his fast will be invalidated. However, if he narrates it as the words of the person who concocted the lie, his fast is not invalidated.
1609. If a person who is fasting is queried whether the prophet (Peace be upon him and his progeny) or one of the Imams (Peace be upon them all) has related a particular matter, and instead of responding in the negative where he needs to do so, he responds affirmatively, or vice-versa, his fast will be invalidated.
1610. If a person relates a true statement from the words of God, the prophet (Peace be upon him and his progeny) or one of the Imams (Peace be upon them all), but later claims to have lied, his fast will be invalidated. The same will apply if he ascribes a lie to them the night before a fast, and then affirms his previous statement on the day of the fast.
