Aya number 24 of surat Sad

[David] said, "He has certainly wronged you in demanding your ewe [in addition] to his ewes. And indeed, many associates oppress one another, except for those who believe and do righteous deeds - and few are they." And David became certain that We had tried him, and he asked forgiveness of his Lord and fell down bowing [in prostration] and turned in repentance [to Allah ].
