4:11
Instructs you Allah concerning your children - for the male like (the) portion (of) two females. But if there are (only) women more (than) two, then for them two thirds (of) what he left. And if (there) is (only) one, then for her (is) half. And for his parents, for each one of them a sixth of what (is) left, if is for him a child. But if not is for him any child and inherit[ed] him his parents, then for his mother (is) one third. And if are for him brothers and sisters, then for his mother (is) the sixth from after any will he has made [of which] or any debt. Your parents and your children - not you know which of them (is) nearer to you (in) benefit. An obligation from Allah. Indeed, Allah is All-Knowing, All-Wise.
