28:52
ٱلَّذِينَ ءَاتَيْنَـٰهُمُ ٱلْكِتَـٰبَ مِن قَبْلِهِۦ هُم بِهِۦ يُؤْمِنُونَ
alladhīna ātaynāhumu l-kitāba min qablihi hum bihi yu'minūna
Those to whom We gave the Scripture before believe in it,
Those to whom We gave the Scripture [i.e. the Taurât (Torah) and the Injeel (Gospel)] before it, they believe in it (the Qur’ân).
