وَأَرْسَلَ عَلَيْهِمْ طَيْرًا أَبَابِيلَ
And He sent against them birds in groups. (الفيل: 3)
The wāw in wa-arsala links this clause to the preceding account. After the plot’s failure is declared, the action associated with that outcome is introduced. The coordination supports narrative cohesion.
Ṭayran is indefinite and abābīla describes birds coming in groups. The expression conveys grouping rather than a precise number, so numerical claims should not be inferred solely from the morphology of abābīl.
