سُنَنَ sunana · (to) ways

Allāh wants to make clear to you [the lawful from the unlawful] and guide you to the [good] practices of those before you and to accept your repentance. And Allāh is Knowing and Wise. (Surah An-Nisa, 4:26)

وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ ٢٦

مَّسْنُونٍ masnūnin · altered

And We did certainly create man out of clay from an altered black mud. (Surah Al-Hijr, 15:26)

وَكَتَبْنَا عَلَيْهِمْ فِيهَا أَنَّ النَّفْسَ بِالنَّفْسِ وَالْعَيْنَ بِالْعَيْنِ وَالْأَنفَ بِالْأَنفِ وَالْأُذُنَ بِالْأُذُنِ وَالسِّنَّ بِالسِّنِّ وَالْجُرُوحَ قِصَاصٌ فَمَن تَصَدَّقَ بِهِ فَهُوَ كَفَّارَةٌ لَّهُ وَمَن لَّمْ يَحْكُم بِمَا أَنزَلَ اللَّهُ فَأُولَٰئِكَ هُمُ الظَّالِمُونَ ٤٥

وَالسِّنَّ wal-sina · and the tooth

And We ordained for them therein a life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth, and for wounds is legal retribution. But whoever gives [up his right as] charity, it is an expiation for him. And whoever does not judge by what Allāh has revealed - then it is those who are the wrongdoers [i.e., the unjust]. (Surah Al-Ma'idah, 5:45)
