The Quran

يوصيكُمُ اللَّهُ في أَولادِكُم ۖ لِلذَّكَرِ مِثلُ حَظِّ الأُنثَيَينِ ۚ فَإِن كُنَّ نِساءً فَوقَ اثنَتَينِ فَلَهُنَّ ثُلُثا ما تَرَكَ ۖ وَإِن كانَت واحِدَةً فَلَهَا النِّصفُ ۚ وَلِأَبَوَيهِ لِكُلِّ واحِدٍ مِنهُمَا السُّدُسُ مِمّا تَرَكَ إِن كانَ لَهُ وَلَدٌ ۚ فَإِن لَم يَكُن لَهُ وَلَدٌ وَوَرِثَهُ أَبَواهُ فَلِأُمِّهِ الثُّلُثُ ۚ فَإِن كانَ لَهُ إِخوَةٌ فَلِأُمِّهِ السُّدُسُ ۚ مِن بَعدِ وَصِيَّةٍ يوصي بِها أَو دَينٍ ۗ آباؤُكُم وَأَبناؤُكُم لا تَدرونَ أَيُّهُم أَقرَبُ لَكُم نَفعًا ۚ فَريضَةً مِنَ اللَّهِ ۗ إِنَّ اللَّهَ كانَ عَليمًا حَكيمًا

Muhammad Asad

CONCERNING [the inheritance of] your children, God enjoins [this] upon you:¹ The male shall have the equal of two females' share; but if there are more than two females, they shall have two-thirds of what [their parents] leave behind; and if there is only one daughter, she shall have one-half thereof. And as for the parents [of the deceased], each of them shall have one-sixth of what he leaves behind, in the event of his having [left] a child; but if he has left no child and his parents are his [only] heirs, then his mother shall have one-third; and if he has brothers and sisters, then his mother shall have one-sixth after [the deduction of] any bequest he may have made, or any debt [he may have incurred]. As for your parents and your children - you know not which of them is more deserving of benefit from you: [therefore this] ordinance from God. Verily, God is all-knowing, wise.

In my notes on verses 11-12, which spell out the legal shares of inheritance due to the next of kin, no attempt has been made to analyze all the legal implications of this ordinance. The laws of inheritance are the subject of a special, and very elaborate, branch of Islamic jurisprudence, and their full elucidation would go far beyond the scope of explanatory notes which aim at no more than making the text of the Qur'an accessible to the understanding of the non-specialized reader.
