Arabic text
وَإِذَا يُتۡلَىٰ عَلَيۡهِمۡ قَالُوٓاْ ءَامَنَّا بِهِۦٓ إِنَّهُ ٱلۡحَقُّ مِن رَّبِّنَآ إِنَّا كُنَّا مِن قَبۡلِهِۦ مُسۡلِمِينَ
And when it is recited to them, they say, "We have believed in it; indeed, it is the truth from our Lord. Indeed we were, [even] before it, Muslims [i.e., submitting to Allāh]."
