Those who lie and act deceitfully in this world, while forgetting that they will be called to account in the Hereafter for all that they have done and said, will not be able to find the strength to lie in the Hereafter. Even if they want to lie, Allah will give them no chance to do so, will seal up their mouths, and will enable their bodily parts to declare, against their owner's will, the truth of that which they were made to do.
Allah tells us, in several verses, that all liars will betray themselves:
Allah also informs us of how "a lying sinner" will be punished on the Day of Judgment and of how he or she will reveal what they have concealed within themselves, even though they may have concealed it many years ago:
No indeed! If he does not desist, We will grab him by the forelock, a lying, sinful forelock. Let him call his attendants; We will call the Guards of Hell! No indeed! Do not obey him, but prostrate and draw near. (Surat al-`Alaq, 96:15-19)
Truly man is ungrateful to his Lord, and indeed he bears witness to that. Truly he is fierce in his love of wealth. Does he not know that when the graves are emptied out, and the heart's contents are brought into the open? (Surat al-`Adiyat, 100:6-10)Liars might not be confronted with their lies in this world, for sometimes people do not notice them or, if they do, they might tolerate them. But in the Hereafter, each individual will receive the just reward for all of his or her wrongdoing. In one verse, Allah mentions that those who lie to the angels sent to take their souls at the moment of death, will find their lies rejected, and that they will receive their final "reward":
Those who do not respect the limits set by Allah and make a habit of lying will feel great regret in the Hereafter. Those who have wisdom and a conscience should consider this end, stay away from all lies, both great and small, and always tell the truth.
