Quran Al-Ahqaf 46:5
وَمَنۡ أَضَلُّ مِمَّن يَدۡعُواْ مِن دُونِ ٱللَّهِ مَن لَّا يَسۡتَجِيبُ لَهُۥٓ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِ وَهُمۡ عَن دُعَآئِهِمۡ غَٰفِلُونَ ٥
Translation
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.
