Surah Al-Ahqaf, Verse 5

وَمَنۡ أَضَلُّ مِمَّن يَدۡعُواْ مِن دُونِ ٱللَّهِ مَن لَّا يَسۡتَجِيبُ لَهُۥٓ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِ وَهُمۡ عَن دُعَآئِهِمۡ غَٰفِلُونَ٥

waman aḍallu mimman yadʿū min dūni l-lahi man lā yastajību lahu ilā yawmi l-qiyāmati wahum ʿan duʿāihim ghāfilūna

And who is more astray than he who invokes besides Allāh those who will not respond to him until the Day of Resurrection [i.e., never], and they, of their invocation, are unaware.
