There are as many advantages for truthfulness as there are disadvantages for lying. Truthfulness is one of the most beautiful traits and lying one of the ugliest. The tongue translates man’s external feelings to the outside. Therefore, if lying stems from envy and or enmity, it is one of the most dangerous sign of anger. If it stems from stinginess or habit, it is from the effects of burning lusts of man.
If a man’s tongue becomes poisoned with lying and its filth appears on him, its effects are like the effects of the autumn wind on the leaves of trees. Lying extinguishes the light of man’s existence and lights the fire of treachery in him. It also has an amazing reaction in terminating the ties of unity and harmony between and spreading hypocrisy.
As per the saying of Prophet Mohamed (pbuh): ”The three signs of a hypocrite are: lying, betraying trust and going back on his word (not fulfilling a promise).” Therefore hypocrites are liars, because they lie to themselves.
Noble Qur’an says about them: ”In their heart, there is a disease and Allah increases their disease and they shall have a painful chastisement because they lie.” (2:10) ”When the hypocrites come to you, they say: We bear witness that you are most surely Allah’s Messenger; and Allah knows that you are most surely His Messenger, and Allah bears witness that the hypocrites are surely liars.” (63:1)
For people with evil intentions lying is an open door for them to reach their selfish goals by concealing the facts behind their magical words and capturing innocent people with their poisonous lies.
Liars have no time for them to think or reflect. They rarely consider the possible conclusions, claiming that ‘no one will ever discover their secrets’. In their words we find many mistakes and contradictions. Liars will eternally become covered with shame, failure and disgrace. Therefore, it is true to say that ‘liars have bad memories’.
Necessary lying has its limitations. It must stop on the border of necessity. Nevertheless, we should not ignore the fact that lying is a great evil, and that if some harm is removed by lying (when permitted) it is with the view of countering the greater evil with the lesser one.
