The Quran root أ ن ث ’-n-th

يَا أَيُّهَا الَّذِينَ آمَنُوا كُتِبَ عَلَيْكُمُ الْقِصَاصُ فِي الْقَتْلَى الْحُرُّ بِالْحُرِّ وَالْعَبْدُ بِالْعَبْدِ وَالْأُنثَىٰ بِالْأُنثَىٰ فَمَنْ عُفِيَ لَهُ مِنْ أَخِيهِ شَيْءٌ فَاتِّبَاعٌ بِالْمَعْرُوفِ وَأَدَاءٌ إِلَيْهِ بِإِحْسَانٍ ذَٰلِكَ تَخْفِيفٌ مِّن رَّبِّكُمْ وَرَحْمَةٌ فَمَنِ اعْتَدَىٰ بَعْدَ ذَٰلِكَ فَلَهُ عَذَابٌ أَلِيمٌ ١٧٨

وَالْأُنثَىٰ wal-unthā · and the female

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. (Surah Al-Baqarah, 2:178)

فَلَمَّا وَضَعَتْهَا قَالَتْ رَبِّ إِنِّي وَضَعْتُهَا أُنثَىٰ وَاللَّهُ أَعْلَمُ بِمَا وَضَعَتْ وَلَيْسَ الذَّكَرُ كَالْأُنثَىٰ وَإِنِّي سَمَّيْتُهَا مَرْيَمَ وَإِنِّي أُعِيذُهَا بِكَ وَذُرِّيَّتَهَا مِنَ الشَّيْطَانِ الرَّجِيمِ ٣٦

أُنثَىٰ unthā · a female

But when she delivered her, she said, "My Lord, I have delivered a female." And Allāh was most knowing of what she delivered, and the male is not like the female. "And I have named her Mary, and I seek refuge for her in You and [for] her descendants from Satan, the expelled [from the mercy of Allāh]." (Surah Ali 'Imran, 3:36)

يُوصِيكُمُ اللَّهُ فِي أَوْلَادِكُمْ لِلذَّكَرِ مِثْلُ حَظِّ الْأُنثَيَيْنِ فَإِن كُنَّ نِسَاءً فَوْقَ اثْنَتَيْنِ فَلَهُنَّ ثُلُثَا مَا تَرَكَ وَإِن كَانَتْ وَاحِدَةً فَلَهَا النِّصْفُ وَلِأَبَوَيْهِ لِكُلِّ وَاحِدٍ مِّنْهُمَا السُّدُسُ مِمَّا تَرَكَ إِن كَانَ لَهُ وَلَدٌ فَإِن لَّمْ يَكُن لَّهُ وَلَدٌ وَوَرِثَهُ أَبَوَاهُ فَلِأُمِّهِ الثُّلُثُ فَإِن كَانَ لَهُ إِخْوَةٌ فَلِأُمِّهِ السُّدُسُ مِن بَعْدِ وَصِيَّةٍ يُوصِي بِهَا أَوْ دَيْنٍ آبَاؤُكُمْ وَأَبْنَاؤُكُمْ لَا تَدْرُونَ أَيُّهُمْ أَقْرَبُ لَكُمْ نَفْعًا فَرِيضَةً مِّنَ اللَّهِ إِنَّ اللَّهَ كَانَ عَلِيمًا حَكِيمًا ١١

الْأُنثَيَيْنِ l-unthayayni · (of) two females

Allāh instructs you concerning your children [i.e., their portions of inheritance]: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two thirds of one's estate. And if there is only one, for her is half. And for one's parents, to each one of them is a sixth of his estate if he left children. But if he had no children and the parents [alone] inherit from him, then for his mother is one third. And if he had brothers [and/or sisters], for his mother is a sixth, after any bequest he [may have] made or debt. Your parents or your children - you know not which of them are nearest to you in benefit. [These shares are] an obligation [imposed] by Allāh. Indeed, Allāh is ever Knowing and Wise. (Surah An-Nisa, 4:11)
