Surat Al-Maaida (The Table) - المائدة

فَطَوَّعَتْ لَهُۥ نَفْسُهُۥ قَتْلَ أَخِيهِ فَقَتَلَهُۥ فَأَصْبَحَ مِنَ ٱلْخَٰسِرِينَ ﴿٣٠﴾ فَبَعَثَ ٱللَّهُ غُرَابًا يَبْحَثُ فِى ٱلْأَرْضِ لِيُرِيَهُۥ كَيْفَ يُوَٰرِى سَوْءَةَ أَخِيهِ قَالَ يَٰوَيْلَتَىٰٓ أَعَجَزْتُ أَنْ أَكُونَ مِثْلَ هَٰذَا ٱلْغُرَابِ فَأُوَٰرِىَ سَوْءَةَ أَخِى فَأَصْبَحَ مِنَ ٱلنَّٰدِمِينَ﴿٣١﴾

Then his mind facilitated to him the slaying of his brother so he slew him; then he became one of the losers Then Allah sent a crow digging up the earth so that he might show him how he should cover the dead body of his brother. He said: Woe me! do I lack the strength that I should be like this crow and cover the dead body of my brother? So he became of those who regret.
