﴿ إِنَّ ٱلَّذِينَ تَدْعُونَ مِن دُونِ ٱللَّهِ عِبَادٌ أَمْثَالُكُمْ ۖ فَٱدْعُوهُمْ فَلْيَسْتَجِيبُوا۟ لَكُمْ إِن كُنتُمْ صَٰدِقِينَ ﴾

“Verily, all those whom you invoke beside God are but created beings like yourselves: invoke them, then, and let them answer your prayer - if what you claim is true!”

The Holy Prophet ﷺ has been asked to say to the unbelievers that your false gods are nothing but slaves like you, and being devoid of essential faculties of moving, seeing, hearing and speaking cannot help themselves, far from coming to your help in your need. If you are not sure, then "Call them and they should respond to you," and "Call to your associate-gods, then plot against me and allow me no respite."
