A Satanic wile corrupting the life of society is this: it is not to see all the virtues of a believer on account of a single bad point. Those unjust people who heed this wile of Satan's are inimical to believers in that way. However when Almighty God weighs up deeds with absolute justice on the supreme scales at the Last Judgement. He will judge in accordance with the predominance of good deeds over evils and vice versa. And since the causes of evil deeds are numerous and their existence is easy sometimes He veils many bad deeds with a single good deed.
That is to say dealings in this world should be in accordance with that Divine justice. If a person's good points are greater in regard to quality or quantity than his bad points the man is deserving of love and respect. Indeed one should forgive numerous bad points on account of a single valuable virtue. However due to the vein of tyranny in his nature and through the promptings of Satan man forgets the hundred virtues of a person because of a single bad point is hostile towards his believing brother and commits sins. Like a fly's wing covering the eye conceals a mountain so too due to the veil of hatred man conceals virtues as great as a mountain due to one evil like a fly's wing; he forgets them is hostile towards his brother believer and becomes a tool of corruption in the life of society.
Through another wile resembling this one. Satan corrupts the wholeness of peoples' thoughts. He destroys sound judgement concerning the truths of belief and damages integrity and correctness of thought. It is like this:
He wants to destroy hundreds of evidences proving the truths of belief through a slight hint refuting them. Whereas it is an established principle that "A single proof is superior to a hundred denials." The statement of a witness proving a claim is preferable to a hundred people denying it. Consider this truth by means of the following comparison:
There is a palace with a hundred doors all closed. On one of its doors being opened the palace may be entered and the other doors opened. If all the doors are open and one or two are closed it may not be said that the palace cannot be entered.
Thus the truths of belief are the palace. Each evidence is a key; it proves the truths and opens a door. If one of the doors remains closed the truths of belief cannot be abandoned and denied. Satan however as a consequence of certain things or by means of heedlessness or ignorance points out a door that has remained closed thus causing a person to disregard all the positive evidences. Saying: "See this palace cannot be entered. Perhaps it is not a palace and there is nothing inside it." he deceives the person.
O my dear friends afflicted by the wiles of Satan! If you want the life of religion and of society and personal life all to be healthy and if you want integrity of thought a sound view and a sincere heart weigh up your actions and thoughts on the scales of the incontestable matters of the Book and the balance of the Practices of the Messenger. Always take the Holy Book the Practices as your guide. Say: I take refuge with God from Satan the Accursed and seek refuge with God Almighty".
