إِنِّيٓ أُرِيدُ أَن تَبُوٓأَ بِإِثۡمِي وَإِثۡمِكَ فَتَكُونَ مِنۡ أَصۡحَٰبِ ٱلنَّارِۚ وَذَٰلِكَ جَزَـٰٓؤُاْ ٱلظَّـٰلِمِينَ
"Verily, I intend to let you draw my sin on yourself as well as yours, then you will be one of the dwellers of the Fire, and that is the recompense of the Zalimun (polytheists and wrong-doers)."
فَطَوَّعَتۡ لَهُۥ نَفۡسُهُۥ قَتۡلَ أَخِيهِ فَقَتَلَهُۥ فَأَصۡبَحَ مِنَ ٱلۡخَٰسِرِينَ
So the Nafs (self) of the other (latter one) encouraged him and made fair-seeming to him the murder of his brother; he murdered him and became one of the losers.
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 crow who scratched the ground to show him to hide the dead body of his brother. He (the murderer) said: "Woe to me! Am I not even able to be as this crow and to hide the dead body of my brother?" Then he became one of those who regretted.
مِنۡ أَجۡلِ ذَٰلِكَ كَتَبۡنَا عَلَىٰ بَنِيٓ إِسۡرَـٰٓءِيلَ أَنَّهُۥ مَن قَتَلَ نَفۡسَۢا بِغَيۡرِ نَفۡسٍ أَوۡ فَسَادٖ فِي ٱلۡأَرۡضِ فَكَأَنَّمَا قَتَلَ ٱلنَّاسَ جَمِيعٗا وَمَنۡ أَحۡيَاهَا فَكَأَنَّمَآ أَحۡيَا ٱلنَّاسَ جَمِيعٗاۚ وَلَقَدۡ جَآءَتۡهُمۡ رُسُلُنَا بِٱلۡبَيِّنَٰتِ ثُمَّ إِنَّ كَثِيرٗا مِّنۡهُم بَعۡدَ ذَٰلِكَ فِي ٱلۡأَرۡضِ لَمُسۡرِفُونَ
Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidences, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allah by committing the major sins) in the land!.
