1. كَذَبتَ وَمَن يَكذِب فَإِنَّ جَزاءهُ

    إِذا ما أَتى بِالصِدقِ أَلا يُصَدَّقا

    You lied, and whoever lies receives this recompense:

    When he tells the truth, he is not believed.

  2. إِذا عُرِفَ الكَذّابُ بِالكِذبِ لَم يَكُن

    لَدى الناسِ ذا صِدقٍ وَإِن كانَ صادِقا

    When a liar is known for lying, he is not

    Considered truthful by people, even if he is truthful.

  3. وَمِن آفَةِ الكَذّابِ نِسيانُ كِذبِه

    وَتَلقاهُ ذا حِفظٍ إِذا كانَ حاذِقا

    And one of a liar's failings is forgetting his lies,

    And you find him with a good memory if he is skillful.
