For you there is one-half of what your wives leave behind, in case they have no child. But, if they have a child, you get one-fourth of what they leave, after (settling) the will they might have made, or a debt. For them (the wives) there is one-fourth of what you leave behind, in case you have no child. But, if you have a child, they get one eighth of what you leave, after (settling) the will you might have made, or a debt. And if a man or a woman is Kalalah (i.e. has neither parents alive, nor children) and has a brother or a sister, then each one of them will get one-sixth. However, if they are more than that, they will be sharers in one-third, after (settling) the will that might have been made, or a debt, provided that the will must not be intended to harm anyone. This is a direction from Allah. Allah is All-Knowing, Forbearing.
