This is because the liar, due to his weakness and his disgracefulness, only seeks protection in his false oaths which he boldly swears to while using Allah's Names, and he uses them (false oaths) all the time and out of place (i.e., unnecessarily).

Ibn `Abbas said, "Al-Mahin means the liar."

Then Allah says

Nor listen to the contemptible who always makes an oath to the truth of his statement because he feels he is not taken at his word nor do his actions to his words accord
