Surah Al-A'raf (The Heights), Verse 194

اِنَّ الَّذِیْنَ تَدْعُوْنَ مِنْ دُوْنِ اللّٰهِ عِبَادٌ اَمْثَالُكُمْ فَادْعُوْهُمْ فَلْیَسْتَجِیْبُوْا لَكُمْ اِنْ كُنْتُمْ صٰدِقِیْنَ ۟

Innal lazeena tad'oona min doonil laahi 'ibaadun amsaalukum fad'oohum fal yastajeeboo lakum in kuntum saadiqeen

“Verily those whom ye call upon besides Allah are servants like unto you: Call upon them, and let them listen to your prayer, if ye are (indeed) truthful!”
