In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Allaah [The Most High] said in Surah Yusuf Aayah 90 that Yusuf’s [alayhis-salaam] brothers said:
قَالُوا أَإِنَّكَ لَأَنْتَ يُوسُفُ ۖ قَالَ أَنَا يُوسُفُ وَهَٰذَا أَخِي ۖ قَدْ مَنَّ اللَّهُ عَلَيْنَا ۖ إِنَّهُ مَنْ يَتَّقِ وَيَصْبِرْ فَإِنَّ اللَّهَ لَا يُضِيعُ أَجْرَ الْمُحْسِنِينَ
They said: “Are you indeed Yusuf (Joseph)? “He said: I am Yusuf (Joseph), and this is my brother (Benjamin). Allah has indeed been gracious to us. Verily, he who fears Allah and is patient, then surely, Allah makes not the reward of the good-doers to be lost.
Few Reminders from the Above Aayah
They knew that the one who addressed them was Yoosuf, so they said: [ أَإِنَّكَ لَأَنْتَ يُوسُف -Are you indeed Yusuf (Joseph)]? Yoosuf said: [أَنَا يُوسُفُ وَهَٰذَا أَخِي ۖ قَدْ مَنَّ اللَّهُ عَلَيْنَا – I am Yusuf (Joseph), and this is my brother (Benjamin). Allah has indeed been gracious to us]-Meaning: By [granting] us Eemaan, piety and authority in the worldly life, and that is due to patience and piety. [ۖ إِنَّهُ مَنْ يَتَّقِ وَيَصْبِرْ -Verily, he who fears Allah and is patient]- Meaning: keeps away from what Allaah has forbidden, exercises patience in facing pain and calamities, and [exercises patience] in carrying out the commandments [of Allaah];
[فَإِنَّ اللَّهَ لَا يُضِيعُ أَجْرَ الْمُحْسِنِين -then surely, Allah makes not the reward of the good-doers to be lost]- Meaning: Because this is from perfection in worship and Allaah does not allow the reward of the one who perfects his deeds to be lost.
