Mughira bin Shuba reported,

A woman struck her co-wife with a tent pole and killed her. The case was brought before the Messenger of Allah ﷺ, who ruled that the killer's paternal male relatives must pay the blood-money. The victim had been pregnant, so he also ruled that the unborn child be compensated with a slave, male or female.One of the killer's relatives objected, "Are we to pay compensation for one who never ate, never drank, never cried out at birth? Such a thing should be disregarded."The Messenger of Allah ﷺ replied, "Rhymed speech like that of the bedouins."

عن المغيرة بن شعبة

أن امرأة قتلت ضرتها بعمود فسطاط فأتي فيه رسول الله ﷺ فقضى على عاقلتها بالدية وكانت حاملا فقضى في الجنين بغرة فقال بعض عصبتها أندي من لا طعم ولا شرب ولا صاح فاستهل ومثل ذلك يطل قال فقال سجع كسجع الأعراب
