The Glorious Qur'an commends those people who listen attentively to it and act accordingly. Knowledgeable men from the People of the Book are described by the Glorious Qur'an as, ((It is) a Qur'an which We have divided (into parts from. time to time), in order that thou mightest recite it to men at intervals: We have revealed it by stages. Say: Whether ye believe in it or not, it is true that those who were given knowledge beforehand, when it recited to them, fall down on their faces in humble prostration. And they say: Glory be to our Lord. Truly has the promise of our Lord been fulfilled. They fall down on their faces in tears, and it increases their (earnest) humility.
Moreover, the Glorious Quran speaks about a group of Christians who embraced Islam, saying,
(And when they listen to the revelation received by the Messenger, thou wilt see their eyes overflowing with tears, for they recognize the truth: they pray: 'Our Lord! We believe; write us down among the witnesses. What cause cart we have not t0 believe in Allah and the truth which has come to us, seeing that we long for our Lord to admit us to the company of the righteous. And for their prayer hath. Allah rewarded them with Gardens, with rivers flowing underneath their eternal home. Such is the recompense of those who do good.
