قَالَ ٱللَّهُ هَٰذَا يَوْمُ يَنفَعُ ٱلصَّٰدِقِينَ صِدْقُهُمْ ۚ لَهُمْ جَنَّٰتٌ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَآ أَبَدًا ۚ رَّضِىَ ٱللَّهُ عَنْهُمْ وَرَضُوا۟ عَنْهُ ۚ ذَٰلِكَ ٱلْفَوْزُ ٱلْعَظِيمُ
9:100; 58:23; 98:9.
Commentary:
The words, This is a day, refer to the Day of Judgement, which shows that the question mentioned in 5:117 above will be put to Jesus on the Day of Judgement, i.e. after he will have paid his supposed second visit to the earth, as is alleged by those who believe in his ascension to, and descent from, heaven.
The word "truthful" used in the verse hints that as the followers of Jesus did not prove truthful, they could not hope to benefit from Divine mercy. The word really refers to Muslims, who were true to the teachings of their Prophet. They believed as he taught them to believe, and acted as he taught them to act, and were true to their God. The word may also refer to the followers of Ahmad, the Promised Messiah, who was raised as the مثیل, or likeness, of Jesus. God, as it were, says, "We sent two Messiahs, the followers of the one drifted away from his teachings and began to look upon him as God, but the followers of the other Messiah were true to his teachings. So this day only the truth of the truthful shall profit them."
