﴿ قَالَ لَقَدْ ظَلَمَكَ بِسُؤَالِ نَعْجَتِكَ إِلَىٰ نِعَاجِهِۦ ۖ وَإِنَّ كَثِيرًۭا مِّنَ ٱلْخُلَطَآءِ لَيَبْغِى بَعْضُهُمْ عَلَىٰ بَعْضٍ إِلَّا ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ وَقَلِيلٌۭ مَّا هُمْ ۗ وَظَنَّ دَاوُۥدُ أَنَّمَا فَتَنَّٰهُ فَٱسْتَغْفَرَ رَبَّهُۥ وَخَرَّ رَاكِعًۭا وَأَنَابَ ۩ ﴾

“Said [David]: “He has certainly wronged thee by demanding that thy ewe be added to his ewes! Thus, behold, do many kinsmen wrong one another [all] save those who believe [in God] and do righteous deeds: but how few are they!” And [suddenly] David understood that We had tried him: and so he asked his Sustainer to forgive him his sin, and fell down in prostration, and turned unto Him in repentance.”
