Quran 28:53 Al-Qasas, ayah 53 of 88

وَإِذَا يُتْلَىٰ عَلَيْهِمْ قَالُوٓا۟ ءَامَنَّا بِهِۦٓ إِنَّهُ ٱلْحَقُّ مِن رَّبِّنَآ إِنَّا كُنَّا مِن قَبْلِهِۦ مُسْلِمِينَ ۝٥٣

28:53 And when it is recited unto them, they say: We believe in it. Lo! it is the Truth from our Lord. Lo! even before it we were of those who surrender (unto Him).
