وَتَوَلَّىٰ عَنْهُمْ وَقَالَ يَـٰٓأَسَفَىٰ عَلَىٰ يُوسُفَ وَٱبْيَضَّتْ عَيْنَاهُ مِنَ ٱلْحُزْنِ فَهُوَ كَظِيمٌ
And he turned away from them and said, "Oh, my sorrow over Joseph," and his eyes became white from grief, for he was [of that] a suppressor.
قَالُوا۟ تَٱللَّهِ تَفْتَؤُا۟ تَذْكُرُ يُوسُفَ حَتَّىٰ تَكُونَ حَرَضًا أَوْ تَكُونَ مِنَ ٱلْهَـٰلِكِينَ
They said, "By Allah, you will not cease remembering Joseph until you become fatally ill or become of those who perish."
يَـٰبَنِىَّ ٱذْهَبُوا۟ فَتَحَسَّسُوا۟ مِن يُوسُفَ وَأَخِيهِ وَلَا تَا۟يْـَٔسُوا۟ مِن رَّوْحِ ٱللَّهِ ۖ إِنَّهُۥ لَا يَا۟يْـَٔسُ مِن رَّوْحِ ٱللَّهِ إِلَّا ٱلْقَوْمُ ٱلْكَـٰفِرُونَ
O my sons, go and find out about Joseph and his brother and despair not of relief from Allah. Indeed, no one despairs of relief from Allah except the disbelieving people."
فَلَمَّا دَخَلُوا۟ عَلَيْهِ قَالُوا۟ يَـٰٓأَيُّهَا ٱلْعَزِيزُ مَسَّنَا وَأَهْلَنَا ٱلضُّرُّ وَجِئْنَا بِبِضَـٰعَةٍ مُّزْجَىٰةٍ فَأَوْفِ لَنَا ٱلْكَيْلَ وَتَصَدَّقْ عَلَيْنَآ ۖ إِنَّ ٱللَّهَ يَجْزِى ٱلْمُتَصَدِّقِينَ
So when they entered upon Joseph, they said, "O 'Azeez, adversity has touched us and our family, and we have come with goods poor in quality, but give us full measure and be charitable to us. Indeed, Allah rewards the charitable."
