Al-Ahqaf - 46:5

وَمَنْ أَضَلُّ مِمَّن يَدْعُو مِن دُونِ اللَّهِ مَن لَّا يَسْتَجِيبُ لَهُ إِلَى يَومِ الْقِيَامَةِ وَهُمْ عَن دُعَائِهِمْ غَافِلُونَ
[46:5]
And who is in greater error than he who calls besides Allah upon those that will not answer him till the day of resurrection and they are heedless of their call?
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)?
And who is further astray than those who, instead of Allah, pray unto such as hear not their prayer until the Day of Resurrection, and are unconscious of their prayer,
