فَبَعَثَ اللّهُ غُرَابًا يَبْحَثُ فِي الأَرْضِ لِيُرِيَهُ كَيْفَ يُوَارِي سَوْءةَ أَخِيهِ قَالَ يَا وَيْلَتَا أَعَجَزْتُ أَنْ أَكُونَ مِثْلَ هَذَا الْغُرَابِ فَأُوَارِيَ سَوْءةَ أَخِي فَأَصْبَحَ مِنَ النَّادِمِينَ
﴿٣١﴾
سورة المائدة
(5/31) Then Allah sent a raven scratching in the earth to show him in what wise he might cover the corpse of his brother. He said: woe unto me was incapable of being like unto this raven so that I might cover the corpse of my brother! And he became of the remorseful.
Surah Al-Ma'idah
