Intentional lying in Quoting the Religious Rulings
Issue No. 1359- If a fasting person intentionally lies in quoting the religious rulings, for example, if he narrates an obligatory thing as a non-obligatory and a haram as a halal, and by this he intends to ascribe it to Almighty Allah or the Holy Prophet (pbuh), his fast is void as an obligatory precaution. However, if his intention is to ascribe the fatwā to a Mujtahid, then he has committed a haram act, but his fast is not void. The same ruling applies also to a person who quotes a doubtful ruling without knowing about it.
