Verse 50

قَالُوٓا۟ أَوَلَمْ تَكُ تَأْتِيكُمْ رُسُلُكُم بِٱلْبَيِّنَـٰتِ قَالُوا۟ بَلَىٰ قَالُوا۟ فَٱدْعُوا۟ وَمَا دُعَـٰٓؤُا۟ ٱلْكَـٰفِرِينَ إِلَّا فِى ضَلَـٰلٍ

They say, did you not receive messengers with proofs? They will say, yes. They will then say, go ahead and call, the calling of the unfaithful is in vain.
