﴿ وَرَبَطْنَا عَلَىٰ قُلُوبِهِمْ إِذْ قَامُوا۟ فَقَالُوا۟ رَبُّنَا رَبُّ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ لَن نَّدْعُوَا۟ مِن دُونِهِۦٓ إِلَٰهًۭا ۖ لَّقَدْ قُلْنَآ إِذًۭا شَطَطًا ﴾

“and endowed their hearts with strength, so that they stood up and said [to one another]: "Our Sustainer is the Sustainer of the heavens and the earth. Never shall we invoke any deity other than Him: [if we did,] we should indeed have uttered an enormity!”

(And We made firm their hearts) We preserved their hearts with faith; it is also said that: We inspired them to hold fast to patience (when they stood forth) when they left the disbelieving emperor Decius (Duqyanus) (and said: Our Lord is the Lord of the heavens and the earth. We cry unto) we worship (no god beside Him, for then should we utter an enormity) for then we would be telling lies and falsehood about Allah.
