And you shall have half of what your wives leave if they have no child, but if they have a child, then you shall have a fourth of what they leave after (payment of) any bequest they may have bequeathed or a debt; and they shall have the fourth of what you leave if you have no child, but if you have a child then they shall have the 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 them 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 that does not harm (others); this is an ordinance from Allah: and Allah is Knowing, Forbearing.

The holders back from among the believers, not having any injury, and those who strive hard in Allah's way with their property and their persons are not equal; Allah has made the strivers with their property and their persons to excel the holders back a (high) degree, and to each (class) Allah has promised good; and Allah shall grant to the strivers above the holders back a mighty reward:

If you do not go forth, He will chastise you with a painful chastisement and bring in your place a people other than you, and you will do Him no harm; and Allah has power over all things.

But if you turn back, then indeed I have delivered to you the message with which I have been sent to you, and my Lord will bring another people in your place, and you cannot do Him any harm; surely my Lord is the Preserver of all things.
