Arabic text
وَرَبَطۡنَا عَلَىٰ قُلُوبِهِمۡ إِذۡ قَامُواْ فَقَالُواْ رَبُّنَا رَبُّ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ لَن نَّدۡعُوَاْ مِن دُونِهِۦٓ إِلَٰهٗاۖ لَّقَدۡ قُلۡنَآ إِذٗا شَطَطًا
And We bound [i.e., 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.
