(39, 40) باب دِيَةِ جَنِينِ الْمَرْأَةِ
It was narrated that Abu Hurairah said:
"Two women of Hudhail had a fight, and one of them threw a rock at the other and killed her and the child in her womb. They referred the dispute to the Messenger of Allah, and the Messenger of Allah ruled that the Diyah for her fetus was a male or female slave, and that the Diyah of the woman be paid by her 'Aqilah (male relatives on the father's side). And he made her children and those who were with them her heirs. Hamal bin Malik bin An-Nabighah Al-Hudhali said: "O Messenger of Allah, how can I pay blood money for one who neither ate nor drank, or shouted such a one should be over looked." The Messenger of Allah said: "This is one of the brothers of the soothsayers" because of the rhyming way in which he spoke.
