Surah Al-Baqarah
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُتِبَ عَلَيْكُمُ ٱلْقِصَاصُ فِى ٱلْقَتْلَى ۖ ٱلْحُرُّ بِٱلْحُرِّ وَٱلْعَبْدُ بِٱلْعَبْدِ وَٱلْأُنثَىٰ بِٱلْأُنثَىٰ ۚ فَمَنْ عُفِىَ لَهُۥ مِنْ أَخِيهِ شَىْءٌ فَٱتِّبَاعٌۢ بِٱلْمَعْرُوفِ وَأَدَآءٌ إِلَيْهِ بِإِحْسَـٰنٍ ۗ ذَٰلِكَ تَخْفِيفٌ مِّن رَّبِّكُمْ وَرَحْمَةٌ ۗ فَمَنِ ٱعْتَدَىٰ بَعْدَ ذَٰلِكَ فَلَهُۥ عَذَابٌ أَلِيمٌ
Yā ayyuhal-lażīna āmanū kutiba ‘alaikumul-qiṣāṣu fil-qatlā, al-ḥurru bil-ḥurri wal-‘abdu bil-‘abdi wal-unṡā bil-unṡā, faman ‘ufiya lahū min akhīhi syai'un fattibā‘um bil-ma‘rūfi wa adā'un ilaihi bi iḥsān(in), żālika takhfīfum mir rabbikum wa raḥmah(tun), fa mani‘tadā ba‘da żālika fa lahū ‘ażābun alīm(un).
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 anything, then there should be a suitable follow-up and payment to him with good conduct. This is an alleviation from your Lord and a mercy. But whoever transgresses after that will have a painful punishment.
