Ghafir 40:50

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

Qālū awalam taku tatīkum rusulukum bil-bayināti qālū balā qālū fa-id'ʿū wamā duʿāu l-kāfirīna illā fī ḍalālin

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]."
