9. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mansur ibn Yunus from abu Basir who has said the following
“I heard Abu ‘Abdillah (a.s.) saying, ‘It is certain that a lie destroys fasting (invalidates it).’ I then said, ‘Who is he among us who is not such a person?’ The Imam said, ‘It is not as you think it is. It is forging lies against Allah, the Messenger of Allah and ‘A’immah, recipients of divine supreme covenant.’”
