176. They request from you a [legal] ruling. Say, "Allāh gives you a ruling concerning one having neither descendants nor ascendants [as heirs]." If a man dies, leaving no child but [only] a sister, she will have half of what he left. And he inherits from her if she [dies and] has no child. But if there are two sisters [or more], they will have two thirds of what he left. If there are both brothers and sisters, the male will have the share of two females.238 Allāh makes clear to you [His law], lest you go astray. And Allāh is Knowing of all things.
Notes
[238] This verse relates to siblings from the father's side or from both parents, whereas in Āyah 12 it concerned those from the mother's side alone.
