Ka`b Ibn Zuhayr (may Allah be pleased with him) stood in front of Allah's Messenger (peace be upon him) and recited his poem, which begins with, "Su`ad has become so far and my heart is left broken ..." However, he never saw Su`ad and nothing happened to him of the matters he mentioned in his poem, thus it is a kind of falsehood. Acting and poetry are kinds of arts, so what do you say about this?
