يَـٰٓأَيُّهَا ٱلنَّاسُ ضُرِبَ مَثَلٞ فَٱسۡتَمِعُواْ لَهُۥٓۚ إِنَّ ٱلَّذِينَ تَدۡعُونَ مِن دُونِ ٱللَّهِ لَن يَخۡلُقُواْ ذُبَابٗا وَلَوِ ٱجۡتَمَعُواْ لَهُۥۖ وَإِن يَسۡلُبۡهُمُ ٱلذُّبَابُ شَيۡـٔٗا لَّا يَسۡتَنقِذُوهُ مِنۡهُۚ ضَعُفَ ٱلطَّالِبُ وَٱلۡمَطۡلُوبُ
O people, an example is presented, so listen to it. Indeed, those you invoke besides Allah 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.
