“Abu Ja’far (a.s.) has said, ‘If a servant maintains pure belief in Allah, the Most Majestic, the Most Holy, for forty days, Allah, the Most Majestic, the Most Holy, purifies his heart in this world and shows him his illnesses and the cure for them (illnesses).’ Also he (a.s.) said, ‘Whenever a servant of Allah speaks of Him in a beautiful way for forty days Allah, the Most Majestic, the Most Holy, purifies his heart in this world and shows him his illnesses and the cure for such illnesses. He then establishes wisdom in his heart and will make his tongue to speak wisdom. ’ The Imam then recited this verse of the Holy Quran, ‘Those who took the calf as their Lord will face anger and humiliation from their Lord in the worldly life and thus, We recompense those who forge lies.’ (7:157) “The Imam said, ‘You should note that all those who forge lies are but despicable persons. So also is one who forges lies against Allah, the Most Majestic, the Most Holy, His messenger and his A hi al-Bayt, recipients of divine supreme covenant. Such person is nothing but a despicable one.’”
