Laws of Inheritance in The Quran
Allah talks about laws of inheritance in the Quran in the following verses in sura nisa.
Sura Nisa (Women) Ayah (Verse) 7-13
٧ لِلرِّجَالِ نَصِيبٌ مِمَّا تَرَكَ الْوَالِدَانِ وَالْأَقْرَبُونَ وَلِلنِّسَاءِ نَصِيبٌ مِمَّا تَرَكَ الْوَالِدَانِ وَالْأَقْرَبُونَ مِمَّا قَلَّ مِنْهُ أَوْ كَثُرَ ۚ نَصِيبًا مَفْرُوضًا
7 Men receive a share of what their parents and relatives leave, and women receive a share of what their parents and relatives leave; be it little or much—a legal share.
٨ وَإِذَا حَضَرَ الْقِسْمَةَ أُولُو الْقُرْبَىٰ وَالْيَتَامَىٰ وَالْمَسَاكِينُ فَارْزُقُوهُمْ مِنْهُ وَقُولُوا لَهُمْ قَوْلًا مَعْرُوفًا
8 If the distribution is attended by the relatives, and the orphans, and the needy, give them something out of it, and speak to them kindly.
٩ وَلْيَخْشَ الَّذِينَ لَوْ تَرَكُوا مِنْ خَلْفِهِمْ ذُرِّيَّةً ضِعَافًا خَافُوا عَلَيْهِمْ فَلْيَتَّقُوا اللَّهَ وَلْيَقُولُوا قَوْلًا سَدِيدًا
9 Those who are concerned about the fate of their weak children, in case they leave them behind, should fear God, and speak appropriate words.
١٠ إِنَّ الَّذِينَ يَأْكُلُونَ أَمْوَالَ الْيَتَامَىٰ ظُلْمًا إِنَّمَا يَأْكُلُونَ فِي بُطُونِهِمْ نَارًا ۖ وَسَيَصْلَوْنَ سَعِيرًا
10 Those who consume the wealth of orphans illicitly consume only fire into their bellies; and they will roast in a Blaze.
١١ يُوصِيكُمُ اللَّهُ فِي أَوْلَادِكُمْ ۖ لِلذَّكَرِ مِثْلُ حَظِّ الْأُنْثَيَيْنِ ۚ فَإِنْ كُنَّ نِسَاءً فَوْقَ اثْنَتَيْنِ فَلَهُنَّ ثُلُثَا مَا تَرَكَ ۖ وَإِنْ كَانَتْ وَاحِدَةً فَلَهَا النِّصْفُ ۚ وَلِأَبَوَيْهِ لِكُلِّ وَاحِدٍ مِنْهُمَا السُّدُسُ مِمَّا تَرَكَ إِنْ كَانَ لَهُ وَلَدٌ ۚ فَإِنْ لَمْ يَكُنْ لَهُ وَلَدٌ وَوَرِثَهُ أَبَوَاهُ فَلِأُمِّهِ الثُّلُثُ ۚ فَإِنْ كَانَ لَهُ إِخْوَةٌ فَلِأُمِّهِ السُّدُسُ ۚ مِنْ بَعْدِ وَصِيَّةٍ يُوصِي بِهَا أَوْ دَيْنٍ ۗ آبَاؤُكُمْ وَأَبْنَاؤُكُمْ لَا تَدْرُونَ أَيُّهُمْ أَقْرَبُ لَكُمْ نَفْعًا ۚ فَرِيضَةً مِنَ اللَّهِ ۗ إِنَّ اللَّهَ كَانَ عَلِيمًا حَكِيمًا
11 God instructs you regarding your children: The male receives the equivalent of the share of two females. If they are daughters, more than two, they get two-thirds of what he leaves. If there is only one, she gets one-half. As for the parents, each gets one-sixth of what he leaves, if he had children. If he had no children, and his parents inherit from him, his mother gets one-third. If he has siblings, his mother gets one-sixth. After fulfilling any bequest and paying off debts. Your parents and your children—you do not know which are closer to you in welfare. This is God’s Law. God is Knowing and Judicious.
١٢ وَلَكُمْ نِصْفُ مَا تَرَكَ أَزْوَاجُكُمْ إِنْ لَمْ يَكُنْ لَهُنَّ وَلَدٌ ۚ فَإِنْ كَانَ لَهُنَّ وَلَدٌ فَلَكُمُ الرُّبُعُ مِمَّا تَرَكْنَ ۚ مِنْ بَعْدِ وَصِيَّةٍ يُوصِينَ بِهَا أَوْ دَيْنٍ ۚ وَلَهُنَّ الرُّبُعُ مِمَّا تَرَكْتُمْ إِنْ لَمْ يَكُنْ لَكُمْ وَلَدٌ ۚ فَإِنْ كَانَ لَكُمْ وَلَدٌ فَلَهُنَّ الثُّمُنُ مِمَّا تَرَكْتُمْ ۚ مِنْ بَعْدِ وَصِيَّةٍ تُوصُونَ بِهَا أَوْ دَيْنٍ ۗ وَإِنْ كَانَ رَجُلٌ يُورَثُ كَلَالَةً أَوِ امْرَأَةٌ وَلَهُ أَخٌ أَوْ أُخْتٌ فَلِكُلِّ وَاحِدٍ مِنْهُمَا السُّدُسُ ۚ فَإِنْ كَانُوا أَكْثَرَ مِنْ ذَٰلِكَ فَهُمْ شُرَكَاءُ فِي الثُّلُثِ ۚ مِنْ بَعْدِ وَصِيَّةٍ يُوصَىٰ بِهَا أَوْ دَيْنٍ غَيْرَ مُضَارٍّ ۚ وَصِيَّةً مِنَ اللَّهِ ۗ وَاللَّهُ عَلِيمٌ حَلِيمٌ
12 You get one-half of what your wives leave behind, if they had no children. If they had children, you get one-fourth of what they leave. After fulfilling any bequest and paying off debts. They get one-fourth of what you leave behind, if you have no children. If you have children, they get one-eighth of what you leave. After fulfilling any bequest and paying off debts. If a man or woman leaves neither parents nor children, but has a brother or sister, each of them gets one-sixth. If there are more siblings, they share one-third. After fulfilling any bequest and paying off debts, without any prejudice. This is a will from God. God is Knowing and Clement.
١٣ تِلْكَ حُدُودُ اللَّهِ ۚ وَمَنْ يُطِعِ اللَّهَ وَرَسُولَهُ يُدْخِلْهُ جَنَّاتٍ تَجْرِي مِنْ تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا ۚ وَذَٰلِكَ الْفَوْزُ الْعَظِيمُ
13 These are the bounds set by God. Whoever obeys God and His Messenger, He will admit him into Gardens beneath which rivers flow, to abide therein forever. That is the great attainment.
Sura Nisa (Women) Ayah (Verse) 174-176
١٧٤ يَا أَيُّهَا النَّاسُ قَدْ جَاءَكُمْ بُرْهَانٌ مِنْ رَبِّكُمْ وَأَنْزَلْنَا إِلَيْكُمْ نُورًا مُبِينًا
174 O people! A proof has come to you from your Lord, and We sent down to you a clear light.
١٧٥ فَأَمَّا الَّذِينَ آمَنُوا بِاللَّهِ وَاعْتَصَمُوا بِهِ فَسَيُدْخِلُهُمْ فِي رَحْمَةٍ مِنْهُ وَفَضْلٍ وَيَهْدِيهِمْ إِلَيْهِ صِرَاطًا مُسْتَقِيمًا
175 As for those who believe in God, and hold fast to Him, He will admit them into mercy and grace from Him, and will guide them to Himself in a straight path.
١٧٦ يَسْتَفْتُونَكَ قُلِ اللَّهُ يُفْتِيكُمْ فِي الْكَلَالَةِ ۚ إِنِ امْرُؤٌ هَلَكَ لَيْسَ لَهُ وَلَدٌ وَلَهُ أُخْتٌ فَلَهَا نِصْفُ مَا تَرَكَ ۚ وَهُوَ يَرِثُهَا إِنْ لَمْ يَكُنْ لَهَا وَلَدٌ ۚ فَإِنْ كَانَتَا اثْنَتَيْنِ فَلَهُمَا الثُّلُثَانِ مِمَّا تَرَكَ ۚ وَإِنْ كَانُوا إِخْوَةً رِجَالًا وَنِسَاءً فَلِلذَّكَرِ مِثْلُ حَظِّ الْأُنْثَيَيْنِ ۗ يُبَيِّنُ اللَّهُ لَكُمْ أَنْ تَضِلُّوا ۗ وَاللَّهُ بِكُلِّ شَيْءٍ عَلِيمٌ
176 They ask you for a ruling. Say, “God gives you a ruling concerning the person who has neither parents nor children.” If a man dies, and leaves no children, and he had a sister, she receives one-half of what he leaves. And he inherits from her if she leaves no children. But if there are two sisters, they receive two-thirds of what he leaves. If the siblings are men and women, the male receives the share of two females.” God makes things clear for you, lest you err. God is Aware of everything.
