I'm currently reading "1001 Nights", the first book, and I realized that a lot of characters seem to be very fond of expressing themselves through poetry, this seems to be true (I haven't finished the book yet) from the Caliph to a peasant fisherman. Not only that, but powerful men being impressed by recitations have saved many lives throughout the book. Why is that?
Edit:
My edition is The Arabian Nights: Tales of 1,001 Nights: Volume 1 (Penguin Classics).

I was wondering if there was a specific motive, maybe historical, regarding the choice of poetry, rather than the author's, whoever it may be, own preference. Therefore, I didn't think that the first Wikipedia article answered my question. But reading the second (which I hadn't read) seems to answer my question:
It was the early poems' importance to Islamic scholarship, though, which would lead to their preservation. Not only did the poems illuminate life in the early years of Islam and its antecedents but they would also prove the basis for the study of linguistics of which the Qur'an was regarded as the pinnacle.
