الاحقاف — Al-Ahqaf Ayat 5
وَمَنْ اَضَلُّ مِمَّنْ يَّدْعُوْا مِنْ دُوْنِ اللّٰهِ مَنْ لَّا يَسْتَجِيْبُ لَهٗٓ اِلٰى يَوْمِ الْقِيٰمَةِ وَهُمْ عَنْ دُعَاۤىِٕهِمْ غٰفِلُوْنَ
Wa man aḍallu mimmay yad‘ū min dūnillāhi mal lā yastajību lahū ilā yaumil-qiyāmati wa hum ‘an du‘ā'ihim gāfilūn(a).
"And who is more astray than he who invokes besides Allah those who will not respond to him until the Day of Resurrection, and they, of their invocation, are unaware."
