إِنْ يَفْعَلَا فَلَقَدْ تَرَكْتُ أَبَاهُمَا جَزَرَ السِّبَاعِ وَكُلِّ نَسْرٍ قَشْعَمِ
If they act, I have already left their father as carrion for beasts of prey and aged vultures.
In yafʿalā is a conditional using the dual. Jazar al-sibāʿ denotes carrion for predators; nasr qashʿam evokes an aged, powerful vulture. The severe final image heightens martial boasting and closes the personal feud narrative, without turning it into a general moral model.
