(Yoosuf) 12 : 90
قَالُوا أَإِنَّكَ لَأَنْتَ يُوسُفُ ۖ قَالَ أَنَا يُوسُفُ وَهَٰذَا أَخِي ۖ قَدْ مَنَّ اللَّهُ عَلَيْنَا ۖ إِنَّهُ مَنْ يَتَّقِ وَيَصْبِرْ فَإِنَّ اللَّهَ لَا يُضِيعُ أَجْرَ الْمُحْسِنِينَ
They asked: "Are you indeed Yoosuf?" He said: "Yes, I am Yoosuf, and this is my brother. Lord Allah has surely favored us; indeed he who heeds Allah and is patient, then indeed Allah doesn't spoil the reward of Muhsins".
Muhsins are those who live under the Light of the Best Book Adhikr as explained in verse 12: 22. The Arabic Quran reading Fujjar have made their food ‘rejecting the Best Interpretation of Lord’s Book’. So at the time of their death Lord will tell them that they were among the disbelievers as told in verse 39: 59. See explanation 10: 26-27.
