Allah (thus) directs you as regards your Children’s (Inheritance): to the male, a portion equal to that of two females: if only daughters, two or more, their share is two-thirds of the inheritance; if only one, her share is a half. For parents, a sixth share of the inheritance to each, if the deceased left children; if no children, and the parents are the (only) heirs, the mother has a third; if the deceased Left brothers (or sisters) the mother has a sixth. (The distribution in all cases (‘s) after the payment of legacies and debts. Ye know not whether your parents or your children are nearest to you in benefit. These are settled portions ordained by Allah; and Allah is All-knowing, Al-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
