Abu Dawud Book 34, Hadith Number 4558.

Chapter : Bloodwit for an unborn child.

Narated By Jabir ibn Abdullah : One of the two women of Hudhayl killed the other, Each of them had husband and sons. The Apostle of Allah (PBUH) fixed the blood-wit for the slain woman to be paid by the woman’s relatives on the father’s side. He declared her husband and the child innocent. The relatives of the woman who killed said: We shall inherit from her. The Apostle of Allah (PBUH) said: No, her sons and her husband should inherit from her.
