An-Nisa 4:11 يوصيكم الله في اولادكم للذكر مثل حظ الانثيين فان كن نساء فوق اثنتين فلهن ثلثا ما ترك وان كانت واحدة فلها النصف ولابويه لكل واحد منهما السدس مما ترك ان كان له ولد فان لم يكن له ولد وورثه ابواه فلامه الثلث فان كان له اخوة فلامه السدس من بعد وصية يوصي بها او دين اباوكم وابناوكم لا تدرون ايهم اقرب لكم نفعا فريضة من الله ان الله كان عليما حكيما ١١

Allâh commands you as regards your children’s (inheritance): to the male, a portion equal to that of two females; if (there are) 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 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 is) after the payment of legacies he may have bequeathed or debts. You know not which of them, whether your parents or your children, are nearest to you in benefit; (these fixed shares) are ordained by Allâh. And Allâh is Ever All-Knower, All-Wise.
