Arabic text
قَالُوٓاْ أَوَلَمۡ تَكُ تَأۡتِيكُمۡ رُسُلُكُم بِٱلۡبَيِّنَٰتِۖ قَالُواْ بَلَىٰۚ قَالُواْ فَٱدۡعُواْۗ وَمَا دُعَـٰٓؤُاْ ٱلۡكَٰفِرِينَ إِلَّا فِي ضَلَٰلٍ
They will say, "Did there not come to you your messengers with clear proofs?" They will say, "Yes." They will reply, "Then supplicate [yourselves], but the supplication of the disbelievers is not except in error [i.e., futility]."
