يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُتِبَ عَلَيْكُمُ ٱلْقِصَاصُ فِى ٱلْقَتْلَى ٱلْحُرُّ بِٱلْحُرِّ وَٱلْعَبْدُ بِٱلْعَبْدِ وَٱلْأُنثَىٰ بِٱلْأُنثَىٰ فَمَنْ عُفِىَ لَهُۥ مِنْ أَخِيهِ شَىْءٌ فَٱتِّبَاعٌۢ بِٱلْمَعْرُوفِ وَأَدَآءٌ إِلَيْهِ بِإِحْسَٰنٍ ذَٰلِكَ تَخْفِيفٌ مِّن رَّبِّكُمْ وَرَحْمَةٌ فَمَنِ ٱعْتَدَىٰ بَعْدَ ذَٰلِكَ فَلَهُۥ عَذَابٌ أَلِيمٌ ١٧٨
O you who have believed, prescribed for you is legal retribution for those murdered - the free for the free, the slave for the slave, and the female for the female. But whoever overlooks from his brother [i.e., the killer] anything, then there should be a suitable follow-up and payment to him [i.e., the deceased's heir or legal representative] with good conduct. This is an alleviation from your Lord and a mercy. But whoever transgresses after that will have a painful punishment.
وَإِذَا حُيِّيتُم بِتَحِيَّةٍ فَحَيُّوا۟ بِأَحْسَنَ مِنْهَآ أَوْ رُدُّوهَآ إِنَّ ٱللَّهَ كَانَ عَلَىٰ كُلِّ شَىْءٍ حَسِيبًا ٨٦
And when you are greeted with a greeting, greet [in return] with one better than it or [at least] return it [in a like manner]. Indeed Allāh is ever, over all things, an Accountant.
إِنَّ ٱللَّهَ يَأْمُرُ بِٱلْعَدْلِ وَٱلْإِحْسَٰنِ وَإِيتَآئِ ذِى ٱلْقُرْبَىٰ وَيَنْهَىٰ عَنِ ٱلْفَحْشَآءِ وَٱلْمُنكَرِ وَٱلْبَغْىِ يَعِظُكُمْ لَعَلَّكُمْ تَذَكَّرُونَ ٩٠
Indeed, Allāh orders justice and good conduct and giving [help] to relatives and forbids immorality and bad conduct and oppression. He admonishes you that perhaps you will be reminded.
وَقُل لِّعِبَادِى يَقُولُوا۟ ٱلَّتِى هِىَ أَحْسَنُ إِنَّ ٱلشَّيْطَٰنَ يَنزَغُ بَيْنَهُمْ إِنَّ ٱلشَّيْطَٰنَ كَانَ لِلْإِنسَٰنِ عَدُوًّا مُّبِينًا ٥٣
And tell My servants to say that which is best. Indeed, Satan induces [dissension] among them. Indeed Satan is ever, to mankind, a clear enemy.
وَٱبْتَغِ فِيمَآ ءَاتَىٰكَ ٱللَّهُ ٱلدَّارَ ٱلْـَٔاخِرَةَ وَلَا تَنسَ نَصِيبَكَ مِنَ ٱلدُّنْيَا وَأَحْسِن كَمَآ أَحْسَنَ ٱللَّهُ إِلَيْكَ وَلَا تَبْغِ ٱلْفَسَادَ فِى ٱلْأَرْضِ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْمُفْسِدِينَ ٧٧
But seek, through that which Allāh has given you, the home of the Hereafter; and [yet], do not forget your share of the world. And do good as Allāh has done good to you. And desire not corruption in the land. Indeed, Allāh does not like corrupters."
