O people, an example is presented, so listen to it. Indeed, those you invoke besides Allāh will never create [as much as] a fly, even if they gathered together for it [i.e., that purpose]. And if the fly should steal from them a [tiny] thing, they could not recover it from him. Weak are the pursuer and pursued.1
Translation: Saheeh International (English)
1 A comparison is made here to the worshipper of a false deity and that which he worships.

Tafsir
O people! A parable is about to be narrated, so listen carefully and take lesson from it! Indeed, those idols and other things you worship instead of Allah cannot even create a fly despite its small size, because of their incompetence. Even if they were to convene in trying to do so they would not be able to achieve it. And if a fly was to take anything away from them, i.e. perfume etc. they would not have the power to reclaim it. By their incapability of creating a fly and reclaiming anything from it, their incapability of doing anything greater than that becomes evident. How can they then worship it instead of Allah? This seeker - which is the worshipped idol that is totally incapable of reclaiming whatever the fly has taken from it, together with the sought-after fly, are both weak.
