الاعراف — Al-A'raf Ayat 194
اِنَّ الَّذِيْنَ تَدْعُوْنَ مِنْ دُوْنِ اللّٰهِ عِبَادٌ اَمْثَالُكُمْ فَادْعُوْهُمْ فَلْيَسْتَجِيْبُوْا لَكُمْ اِنْ كُنْتُمْ صٰدِقِيْنَ
Innal-lażīna tad‘ūna min dūnillāhi ‘ibādun amṡālukum fad‘ūhum falyastajībū lakum in kuntum ṣādiqīn(a).
"Indeed, those you [polytheists] call upon besides Allah are servants like you. So call upon them and let them respond to you, if you should be truthful."
