5:27
وَاتْلُ عَلَيْهِمْ نَبَأَ ابْنَيْ آدَمَ بِالْحَقِّ إِذْ قَرَّبَا قُرْبَاناً فَتُقُبِّلَ مِن أَحَدِهِمَا وَلَمْ يُتَقَبَّلْ مِنَ الآخَرِ قَالَ لَأَقْتُلَنَّكَ قَالَ إِنَّمَا يَتَقَبَّلُ اللّهُ مِنَ الْمُتَّقِينَ
Recite to them the truth of the story of the two sons of Adam. Behold! they each presented a sacrifice (to Allah): It was accepted from one, but not from the other. Said the latter: "Be sure I will slay thee." "Surely," said the former, "Allah doth accept of the sacrifice of those who are righteous.
5:28
لَئِن بَسَطتَ إِلَيَّ يَدَكَ لِتَقْتُلَنِي مَا أَنَاْ بِبَاسِطٍ يَدِيَ إِلَيْكَ لَأَقْتُلَكَ إِنِّي أَخَافُ اللّهَ رَبَّ الْعَالَمِينَ
"If thou dost stretch thy hand against me, to slay me, it is not for me to stretch my hand against thee to slay thee: for I do fear Allah, the cherisher of the worlds.
5:29
إِنِّي أُرِيدُ أَن تَبُوءَ بِإِثْمِي وَإِثْمِكَ فَتَكُونَ مِنْ أَصْحَابِ النَّارِ وَذَلِكَ جَزَاء الظَّالِمِينَ
"For me, I intend to let thee draw on thyself my sin as well as thine, for thou wilt be among the companions of the fire, and that is the reward of those who do wrong."
5:30
فَطَوَّعَتْ لَهُ نَفْسُهُ قَتْلَ أَخِيهِ فَقَتَلَهُ فَأَصْبَحَ مِنَ الْخَاسِرِينَ
The (selfish) soul of the other led him to the murder of his brother: he murdered him, and became (himself) one of the lost ones.
