Qur'an 46:5

وَمَنْ أَضَلُّ مِمَّن يَدْعُوا۟ مِن دُونِ ٱللَّهِ مَن لَّا يَسْتَجِيبُ لَهُۥٓ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ وَهُمْ عَن دُعَآئِهِمْ غَـٰفِلُونَ

“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.”
