فَتَأَوَّتْ لَهُ قَرَاضِبَةٌ مِنْ كُلِّ حَيٍّ كَأَنَّهُمْ أَلْقَاءُ
Meaning: Then fierce and crafty men gathered to him from various tribes, like birds of prey ready to swoop.
Taʾawwat denotes gathering. Qarāḍibah names harsh, cunning or predatory men, explained in the commentary through a thief or raider. Alqāʾ relates to eagles or birds of prey.
Kaʾannahum explicitly introduces a simile. The birds suggest speed and aggression, not moral approval. The many tribal origins also make the assembled force appear extensive and mixed.
