قَالَ ٱلَّذِى عِندَهُۥ عِلْمٌۭ مِّنَ ٱلْكِتَٰبِ أَنَا۠ ءَاتِيكَ بِهِۦ قَبْلَ أَن يَرْتَدَّ إِلَيْكَ طَرْفُكَ ۚ فَلَمَّا رَءَاهُ مُسْتَقِرًّا عِندَهُۥ قَالَ هَٰذَا مِن فَضْلِ رَبِّى لِيَبْلُوَنِىٓ ءَأَشْكُرُ أَمْ أَكْفُرُ ۖ وَمَن شَكَرَ فَإِنَّمَا يَشْكُرُ لِنَفْسِهِۦ ۖ وَمَن كَفَرَ فَإِنَّ رَبِّى غَنِىٌّۭ كَرِيمٌۭ
One with whom was knowledge of the Scripture said: I will bring it thee before thy gaze returneth unto thee. And when he saw it set in his presence, (Solomon) said: This is of the bounty of my Lord, that He may try me whether I give thanks or am ungrateful. Whosoever giveth thanks he only giveth thanks for (the good of) his own soul; and whosoever is ungrateful (is ungrateful only to his own soul's hurt). For lo! my Lord is Absolute in independence, Bountiful.
