Overall meaning :
The Almighty makes mention of the blessings that He bestowed upon the Children of Israel, saying: We then settled the Israelites into fine dwellings, and We provided good things for their sustenance in the Blessed Land. They did not differ—in that some of them acknowledged Prophet Muhammad, may Allah bless him and grant him peace, who fits the description of the prophet who was foretold in their Book, while some others didn’t—until what they knew deep down in theirs hearts to be the truth came to them, namely, when the Qur’an came down making it clear that he is a true messenger and his religion is the truth. Your Lord, Muhammad, will judge their differences regarding you on the Day of Judgement and, as a result, will admit those who disbelieve you into Hell and those who believe you into Paradise. If you are in doubt, Messenger, about what We have informed—namely that the Children of Israel did not differ regarding you until your advent, as they find you fit the description of the prophet they were foretold in the Torah and is clearly written in their books—then ask those who read the Torah and the Gospel revealed before your time, for that is truly confirmed in their books.
The absolute truth that you are Allah’s Messenger has now come to you from your Lord, and these Jews and Christians know this is the truth, for they find your description clearly written in their books but they deny it despite their knowing of it. Therefore, do not be of those who entertain doubts about this; nor be of those who reject the verses of the Qur’an, otherwise you will be among the losers who have earned Allah’s wrath and become justly deserving of His punishment.
