﴿ قَالَ بَلْ سَوَّلَتْ لَكُمْ أَنفُسُكُمْ أَمْرًۭا ۖ فَصَبْرٌۭ جَمِيلٌ ۖ عَسَى ٱللَّهُ أَن يَأْتِيَنِى بِهِمْ جَمِيعًا ۚ إِنَّهُۥ هُوَ ٱلْعَلِيمُ ٱلْحَكِيمُ ﴾

“[AND WHEN they returned to their father and told him what had happened,] he exclaimed: "Nay, but it is your [own] minds that have made [so terrible] a happening seem a matter of little account to you! But [as for myself,] patience in adversity is most goodly; God may well bring them all [back] unto me: verily, He alone is all-knowing, truly wise!"”
