it is not really poetry, because the writer did not deliberately intend to produce the rhythm!
The same excuse is urged for the lines which Muḥammad is related to have uttered impromptu when his toe was wounded in battle:—
هل انت الا اصبع دميت
و فى سبيل الله ما لقيت
Hal anti illā iṣbaʿun damīti?
Wa fī sabīli ʾllāhi mā laqīti.
“Art thou anything but a toe covered with blood?
“What has happened to thee has been in the road of God.”
Arabic scholars (see Kashfu Īṣt̤ilāḥāti ʾl-Funūn, in loco) divide the Arabic poets into six periods:—
(1) Al-Jāhilīyūn, those in the time of ignorance, or before Islām, such as the ancient Arabic poets Zuhair, T̤arafah, Imru ʾl-Qais, ʿAmr ibn Kuls̤ūm, al-Ḥāris̤, and ʿAntarah.
