Surah Al-A'raf — Ayah 192 (7:192)
وَلَا يَسۡتَطِيعُونَ لَهُمۡ نَصۡرٗا وَلَآ أَنفُسَهُمۡ يَنصُرُونَ ١٩٢
English translation (Saheeh International)
And they [i.e., the false deities] are unable to [give] them help, nor can they help themselves.
Brief commentary
These things that are worshipped instead of Allah cannot help those who worship them, and cannot even help themselves, so worshipping them is clearly foolish and ignorant.
