الكهف — Al-Kahf Ayat 14
وَّرَبَطْنَا عَلٰى قُلُوْبِهِمْ اِذْ قَامُوْا فَقَالُوْا رَبُّنَا رَبُّ السَّمٰوٰتِ وَالْاَرْضِ لَنْ نَّدْعُوَا۟ مِنْ دُوْنِهٖٓ اِلٰهًا لَّقَدْ قُلْنَآ اِذًا شَطَطًا
Wa rabaṭnā ‘alā qulūbihim iż qāmū fa qālū rabbunā rabbus-samāwāti wal-arḍi lan nad‘uwa min dūnihī ilāhal laqad qulnā iżan syaṭaṭā(n).
"And We made firm their hearts when they stood up and said, "Our Lord is the Lord of the heavens and the earth. Never will we invoke besides Him any deity. We would have certainly spoken, then, an excessive transgression."
