Ascribing Lies to Allah
Issue No. 1354- If a person, who is observing fast, intentionally ascribes something false to Allah and the Prophet (pbuh) and his vicegerent (a.s.), verbally or in writing or by making a sign, his fast becomes void , as an obligatory precaution, even if he may at once repent for it. The same ruling also applies to imputing lies to all the other prophets and to Fatima Zahra (a.s.).
