4/An-Nisa-12: And for you is the half of what your wives (women) leave if they have no child. But if they (women) have a child, then for you is one fourth. This is after (payment of) any bequest they may have bequeathed or a debt. And to them (women) belongs the fourth of what you leave if you have no child; but if you leave a child, then for them is an eighth of what you leave after (payment of) a bequest you may have bequeathed or a debt. And if a man or a woman leaves property to be inherited by neither parents nor offspring, and he (or she) has a brother or a sister, then each of the two shall have the sixth, but if they are more than that, they shall be sharers in the third after (payment of) any bequest that may have been bequeathed or a debt as long as there is no detriment (to anyone). (These are) the devise (to you) from Allah; and Allah is All-Knowing, Most-Gentle.
4/An-Nisa-13: These are the limits of Allah; and whoever obeys Allah and His Messenger, He will cause them to enter Heavens beneath which the rivers flow, to abide in them forever; and this is Fevzul Azîm (the greatest salvation).
