quran:2:121 –

Those to whom We have given the Book recite it with its true recital. They ˹are the ones who˺ believe in it. And whoever disbelieves in it - it is they who are the losers.  

Those to whom We have given the Scripture (this is the subject of the sentence), and who recite it with true recitation, that is, who recite it as it was revealed (haqqa tilāwatihi, ‘its true recitation’, is a circumstantial qualifier; haqqa is in the accusative because it is the object of the verbal noun), they believe in it (this is the predicate): this was revealed concerning a group of Ethiopians that presented themselves ˹to the Prophet˺ and accepted Islam; and whoever disbelieves in it, that is, in the revealed Book, by distorting it, they shall be the losers, because they will be destined for the Fire, made everlasting for them.
القرآن:٢:١٢١ –

الَّذِينَ آتَيْنَاهُمُ الْكِتَابَ يَتْلُونَهُ حَقَّ تِلَاوَتِهِ أُولَٰئِكَ يُؤْمِنُونَ بِهِ ۗ وَمَنْ يَكْفُرْ بِهِ فَأُولَٰئِكَ هُمُ الْخَاسِرُونَ  

{الذين آتيناهم الكتاب} مبتدأً {يتلونه حق تلاوته} أي يقرؤونه كما أنزل والجملة حال وحق نصب على المصدر والخبر {أولئك يؤمنون به} نزلت في جماعة قدموا من الحبشة وأسلموا {ومن يكفر به} أي بالكتاب المؤتى بأن يحرفه {فأولئك هم الخاسرون} لمصيرهم إلى النار المؤبدة عليهم.
