مِكَرٍّ مِفَرٍّ مُقْبِلٍ مُدْبِرٍ مَعًا
كَجُلْمُودِ صَخْرٍ حَطَّهُ السَّيْلُ مِنْ عَلِ
“Quick to wheel and retreat, advancing and withdrawing together—like a huge mass of rock driven down from a height by a torrent.”
Mikarr, mifarr, muqbil, mudbir, maʿan crowds four changes of motion into a single line. It is not a literal claim that the horse occupies contradictory directions simultaneously; the compression expresses how quickly it can reverse its movement.
Ka-julmūdi ṣakhr invokes a massive rock; ḥaṭṭahu al-saylu min ʿal adds a torrent's powerful downward force. The combination expresses both agility and momentum, qualities of a capable riding and hunting horse.
