Allah commands you concerning (inheritance of) your children: The share of a son is equal to that of two daughters; then if there are only daughters (two or) more, they are entitled to two-thirds of the inheritance; if there is only one daughter, her share will be one half; the mother and the father of the deceased will get one-sixth of the inheritance each, if the deceased leaves children behind; but in case the deceased has no children and the heirs are only his mother and his father, the mother’s share is one-third (and the rest is the father’s); then, if he has brothers and sisters, the mother will have a sixth portion. This distribution will be (executed) after (the fulfilment of) the will he may have made or after (the payment of) the debt. You know not which of them, whether your parents or your sons, are closer to you in bringing you benefit. This (distribution) is a duty assigned (i.e. fixed) by Allah. Surely, Allah is All-Knowing, Most Wise.
