Those who disbelieved from the People of the Scripture were the Jews. There were also some of the remaining polytheists in Medina. These two groups of people did not wish that the verses would be revealed to Rasulullah r.This was because, they contained the goodness of both the world and the hereafter. Furthermore, Allah U had revealed them to the heart of an Arabian Prophet, something which they had not wished to happen. However, Allah selects for His gift whom He wills. And Allah U has reserved for our Prophet r this Holy Qur’an as a grace from Him, as Allah U says:
﴾وَكَانَ فَضْلُ اللَّهِ عَلَيْكَ عَظِيماً﴿
“And ever has the favour of Allah upon you been great.”
[Surah An-Nisaa’: 113] and
﴾اللَّهُ أَعْلَمُ حَيْثُ يَجْعَلُ رِسَالَتَهُ ﴿ “Allah is most knowing of where He places His message.” [Surah Al-An’aam: 124].
