Surah Al-Hajj (The Pilgrimage), Verse 73

یٰۤاَیُّهَا النَّاسُ ضُرِبَ مَثَلٌ فَاسْتَمِعُوْا لَهٗ اِنَّ الَّذِیْنَ تَدْعُوْنَ مِنْ دُوْنِ اللّٰهِ لَنْ یَّخْلُقُوْا ذُبَابًا وَّلَوِ اجْتَمَعُوْا لَهٗ وَاِنْ یَّسْلُبْهُمُ الذُّبَابُ شَیْـًٔا لَّا یَسْتَنْقِذُوْهُ مِنْهُ ضَعُفَ الطَّالِبُ وَالْمَطْلُوْبُ ۟

Yaaa ayyuhan naasu duriba masalun fastami'oo lah; innal lazeena tad'oona min doonil laahi lai yakhluqoo zubaabanw wa lawijtama'oo lahoo wa iny yaslub humuz zubaabu shai'an laa yastanqizoohu minh; da'ufat taalibu wal matloob

“O men! Here is a parable set forth! listen to it! Those on whom, besides Allah, ye call, cannot create (even) a fly, if they all met together for the purpose! and if the fly should snatch away anything from them, they would have no power to release it from the fly. Feeble are those who petition and those whom they petition!”
