Surah Al-Ahqaf (The Sand-Hills), Verse 5

وَمَنْ اَضَلُّ مِمَّنْ یَّدْعُوْا مِنْ دُوْنِ اللّٰهِ مَنْ لَّا یَسْتَجِیْبُ لَهٗۤ اِلٰی یَوْمِ الْقِیٰمَةِ وَهُمْ عَنْ دُعَآىِٕهِمْ غٰفِلُوْنَ ۟

Wa man adallu mimmany yad'oo min doonil laahi mallaa yastajeebu lahooo ilaa Yawmil Qiyaamati wa hum'an du'aaa'ihim ghaafiloon

“And who is more astray than one who invokes besides Allah, such as will not answer him to the Day of Judgment, and who (in fact) are unconscious of their call (to them)?”

Quran 46:5 (Yusuf Ali Translation)
