Surah Al-A'raf — Ayah 197 (7:197)
وَٱلَّذِينَ تَدۡعُونَ مِن دُونِهِۦ لَا يَسۡتَطِيعُونَ نَصۡرَكُمۡ وَلَآ أَنفُسَهُمۡ يَنصُرُونَ ١٩٧
English translation (Saheeh International)
And those you call upon besides Him are unable to help you, nor can they help themselves."
Brief commentary
Those you call upon O idolators from amongst these idols, are not able to help you, and are not able to help themselves. For they are utterly incapable, unable to do anything. So how can you call upon them instead of calling upon Allah?
