Those to whom We gave the Scripture before it - they are meaning

*72) This dces not mean that all the people of the Book (the Jews and the Christians) affirm faith in it. This, in fact, contains an allusion to the event that occurred during the period when this Surah was revealed, and was meant to put to shame the people of Makkah, as if to say, "You are denying and rejecting a blessing that has been sent in your own city, whereas the people from far off places, when they hear of it, come to recognize its worth and benefit from it."
This event has been related by lbn Hisham, Baihaqi and others on the authority of Ibn Ishaq, thus: "After the migration to Habash when the news about the Holy Prophet's advent and message spread in that land, a deputation of about twenty Christians came to Makkah to find out the truth, and they met the Holy Prophet in the Masjid-al-Haram A crowd of the Quraish also gathered around them to watch what happened. The members of the deputation asked the Holy Prophet some questions, which he answered. Then he invited them to accept Islam and recited some verses of the Qur'an before them. When they heard the Qur'an, tears came down from their eyes and they confirmed its being Allah's Word and believed in the Holy Prophet. When the meeting was over and the people left, Abu Jahl and some of his men overtook them on the way, and rebuked them severely, saying, "Never has a more stupid company come here before: O foolish men you were sent here by your people with a view to inquiring about this man. but no sooner did you meet him than you gave up your own faith! " Those gentle people answered, "Peace be to you! We have no wish to enter all argument with you: you are responsible for your faith and we are for ours: we cannot afford to deprive ourselves knowingly of goodness." (Ibn Hisham, Vol. II, p. 32; Al-Bidayah wanNihayah, Vol. III, p. 82. For further details, see E.N. 123 of Ash-Shu`araa).
