[Nisa 4:12] And from what your wives leave, half is for you if they do not have any child; or if they have a child for you is a fourth of what they leave, after any will they may have made or debt to be paid; and to the women is a fourth of what you leave behind, if you do not have any child; or if you have a child then an eighth of what you leave behind, after any will you may have made, or debt to be paid; and if a deceased does not leave behind a mother, father or children but has a brother or a sister through a common mother, then to each of them a sixth; and if they (brothers and sisters) are more than two, then they shall all share in a third, after any will that may have been made or debt to be paid, in which the deceased has not caused a loss (to the heirs); this is the decree of Allah; and Allah is All Knowing, Most Forbearing.

[Nisa 4:13] These are the limits of Allah; and whoever obeys Allah and His Noble Messenger - Allah will admit him into Gardens beneath which rivers flow - abiding in it forever; and this is the great success.

[Nisa 4:14] And whoever disobeys Allah and His Noble Messenger and crosses all His limits - Allah will put him in the fire (of hell), in which he will remain forever; and for him is a disgraceful punishment.
