I learned a verse of the Qur'an that no man has ever asked me about and I do not know whether the people knew about it and so did not ask me about it, or they were not aware of it and that is why they did not ask about it. Then he started talking to us, and when he stood up to leave, we regretted that we had not asked him about it. I said I will ask him when I see him tomorrow. When the next day came, I said: O Ibn 'Abbas, yesterday you said that there was a verse in the Qur'an that no man ever asked you about, and you did not know whether the people knew it and so did not ask about it, or they were not aware of it. I said: Tell me about it and about the verses before it. He said: Yes. The Messenger of Allah (ﷺ) said to Qurraish: "O Quraish, there is no goodness in anyone who is worshipped instead of Allah." Quraish knew that the Christians worship Eesa Ibn Maryam, so they said: O Muhammad, didn't you say that "Eesa was a Prophet and one of the righteous slaves of Allah? If you are telling the truth, then their gods are also as you say. Then Allah, may He be glorified and exalted, revealed the words: "And when the son of Maryam (Mary) is quoted as an example [i.e. Eesa (Jesus) is worshipped like their idols], behold, your people cry aloud (laugh out at the example)" [azZukhruf 43:57]. I said: What does yasiddoona (cry aloud) mean? He said: Make noise. "And he "Eesa (Jesus), son of Maryam (Mary)] shall be a known sign for (the coming of) the Hour” [az-Zukhruf 43.61). He said: That is the appearance of "Eesa Ibn Maryam before the Day of Resurrection.
