﴿ وَإِذَا يُتْلَىٰ عَلَيْهِمْ قَالُوٓا۟ ءَامَنَّا بِهِۦٓ إِنَّهُ ٱلْحَقُّ مِن رَّبِّنَآ إِنَّا كُنَّا مِن قَبْلِهِۦ مُسْلِمِينَ ﴾

“and whenever it is [clearly] conveyed unto them, they [are bound to] profess, “We have come to believe in it, for, behold, it is the truth from our Sustainer - and, verily, even before this have we surrendered ourselves unto Him!””

(And when it is recited unto them) and when the Qur'an is recited to them expositing the attributes and description of Muhammad (pbuh) (they say: We believe in it) we believe in Muhammad (pbuh) and in the Qur'an. (Lo! it is the Truth from our Lord. Lo! even before it) before the recitation of the Qur'an to us (we were of those who surrender (unto Him)) we were of those who believe in Muhammad (pbuh) and the Qur'an.
