الآية رقم (119) - قَالَ اللّهُ هَذَا يَوْمُ يَنفَعُ الصَّادِقِينَ صِدْقُهُمْ لَهُمْ جَنَّاتٌ تَجْرِي مِن تَحْتِهَا الأَنْهَارُ خَالِدِينَ فِيهَا أَبَدًا رَّضِيَ اللّهُ عَنْهُمْ وَرَضُواْ عَنْهُ ذَلِكَ الْفَوْزُ الْعَظِيمُ

(119) - (Allah will say, "This is the Day when the truthful will benefit from their truthfulness." For them are gardens [in Paradise] beneath which rivers flow, wherein they will abide forever, Allah being pleased with them, and they with Him. That is the great attainment.)

This is because, truthfulness and sincerity in the world will lead to receiving benefit in the hereafter, for when a person is truthful to his Lord, he will attain His Pleasure.

(… رَّضِيَ اللَّهُ عَنْهُمْ وَرَضُوا عَنْهُ ۚ… ) (…Allah being pleased with them, and they with Him. ): That is, they will be pleased with Allah’s gifts, for in Paradise are blessings which no eye has ever seen, no ear has ever heard of, and no human heart has ever thought of. And that is the ultimate triumph.
