In the preceding verses, the Jews have been warned of the consequences of their attitude towards the Qur'an and the mission of the Holy Prophet. In this part of the verse, they have been admonished to consider the matter from another point of view. As the Qur'an shows the way to right guidance and brings good tidings to the believers, it is sheer folly to oppose it and reject it. Thus ney harm none but themselves by depriving themselves of the true success which follows its acceptance.
