Al Kahf Ayah 14

وَرَبَطْنَا عَلَىٰ قُلُوبِهِمْ إِذْ قَامُواْ فَقَالُواْ رَبُّنَا رَبُّ ٱلسَّمَـٰوَٲتِ وَٱلْأَرْضِ لَن نَّدْعُوَاْ مِن دُونِهِۦٓ إِلَـٰهًا‌ۖ لَّقَدْ قُلْنَآ إِذًا شَطَطًا ١٤ And We strengthened their hearts when they stood up and declared, “Our Lord is the Lord of the heavens and the earth. We will never call upon any god besides Him, or we would truly be uttering an outrageous lie.”
