غافر — Ghafir Ayat 50
قَالُوْٓا اَوَلَمْ تَكُ تَأْتِيْكُمْ رُسُلُكُمْ بِالْبَيِّنٰتِ ۗقَالُوْا بَلٰىۗ قَالُوْا فَادْعُوْا ۚوَمَا دُعٰۤؤُا الْكٰفِرِيْنَ اِلَّا فِيْ ضَلٰلٍ ࣖ
Qālū awalam taku ta'tīkum rusulukum bil-bayyināt(i), qālū balā, qālū fad‘ū, wa mā du‘ā'ul-kāfirīna illā fī ḍalāl(in).
"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.""
