Al-A'raf 7:193

Wa-in tadAAoohum ila alhuda layattabiAAookum sawaon AAalaykum adaAAawtumoohum am antum samitoon

And if you [believers] invite them to guidance, they will not follow you. It is all the same for you whether you invite them or you are silent.

If you call them to the right path, they will not follow you. It is all the same for them whether you call them or remain silent.
