What is the validity of the argument that the meaning of istiwaa' (rising above the Throne) is istiwa' (seizing control), based on the poet's saying: "Bishr has seized control of Iraq"?

Question:
Those who say that the meaning of istiwaa' (rising above the Throne) is istiwa' (seizing control) argue using the poet's line: "Bishr has seized control of Iraq without a sword or spilled blood." They ask: How do we respond to this?

Answer:
This poem is fabricated. It was not found in the diwan (collection of poetry) attributed to him. The meaning of istiwaa' (rising above the Throne) is not istiwa' (seizing control). It is not in the language of the Arabs for istiwaa' (rising above the Throne) to mean istiwa' (seizing control). Yes.
