The previous verse told us how the Jews behaved towards the Holy Prophet ﷺ ; the present verse speaks of their behaviour towards Muslims in general. Some of the Jews used to assure the Muslims of their sincerity towards them, and to pretend that they would very much have liked the Muslims to. have received from Allah religious doctrines and commandments superior to what they themselves had received, so that they too could accept them, but unfortunately Islam did not seem to be a better religion. The Holy Qur'an refutes their claim to be the well-wishers of the Muslims, and declares that the infidels, whether they be the Jews or the associators, are so jealous of Muslims that they can never like the idea of their receiving from Allah any kind of blessing whatsoever. Of course, this jealousy can do no harm to the Muslims, for Allah is Beneficent and All-Powerful, and can shower his special blessings on whomsoever He chooses.
These Jews used to make two claims -- firstly, that Judaism was a better religion than Islam; secondly, that they were the well-wishers of the Muslims. They could not establish the first of these claims on the basis of any valid argument, and it remained an empty assertion. Moreover, the difference between Islam and Judaism does not primarily depend on the question of one being better than the other. For, when something new comes to abrogate something older, the latter is automatically given up -- and Allah has sent Islam to abrogate all the earlier religions. The fact being so obvious, the Holy Qur'an says nothing in refutation of the first claim, and takes up only the second. The mushrikin مشرکین (associators) have been mentioned here along with the Jews for the sake of emphasis, and to point out that Jews cannot be the well-wishers of Muslims any more than mushrikin مشرکین can -- the two being alike in their hatred of Muslims.
