Key Verses

1. 5:31Al-Maidah
   فَبَعَثَ ٱللَّهُ غُرَابٗا يَبۡحَثُ فِي ٱلۡأَرۡضِ لِيُرِيَهُۥ كَيۡفَ يُوَٰرِي سَوۡءَةَ أَخِيهِۚ قَالَ يَٰوَيۡلَتَىٰٓ أَعَجَزۡتُ أَنۡ أَكُونَ مِثۡلَ هَٰذَا ٱلۡغُرَابِ فَأُوَٰرِيَ سَوۡءَةَ أَخِيۖ فَأَصۡبَحَ مِنَ ٱلنَّـٰدِمِينَ
   Then Allah sent a raven scratching up the ground, to show him how to hide his brother's naked corpse. He said: Woe unto me! Am I not able to be as this raven and so hide my brother's naked corpse? And he became repentant.
   In context

   Allah sent a crow to dig the earth in front of him to bury another dead crow and teach him how to cover his brother’s body. He then became regretful. Regret is the end result of those who commit sins.
