هِرٌّ جَنِيبٌ كُلَّمَا عَطَفْتُ لَهُ غَضْبَى اتَّقَاهَا بِالْيَدَيْنِ وَبِالْفَمِ
It is like a strange cat: whenever I turn the irritable animal toward it, the cat wards off the attack with its paws and mouth.
Hirr janīb gives the image of an unfamiliar cat. Kullamā ʿaṭaftu makes the turning recurrent, while ghaḍbā conveys anger or agitation. The cat resists with paws and mouth.
Ittaqāhā bi-l-yadayn wa-bi-l-fam specifies the instruments of defence. In the broader description the comparison gives the moving she-camel tension and resistance, not simply speed.
