القياس الشعري قياس مؤلف من المخيلات الصادقة، أو الكاذبة المستحيلة، أو الممكنة
A poetic syllogism is formed from imaginative premises that may be true, or false with impossible or possible content.
The key term is mukhayyalāt: statements that produce an image or felt impression in the audience. Poetic character does not depend simply on whether the statement is true or false; its imaginative effect is decisive.
Thus a factually true statement may be expressed poetically, and an exaggeration or impossible image may also function as poetic material.
