Abu Dawud Book 34, Hadith Number 4561.
Chapter : Bloodwit for an unborn child.
Narated By Buraydah ibn al-Hasib : A woman threw a stone at another woman and she aborted. The dispute was brought to the Apostle of Allah (PBUH). He gave judgment that five hundred sheep should be paid for her (unborn) child, and forbade throwing stones.
Abu Dawud said: The version of this tradition goes in this way, i.e. five hundred sheep. What is correct is one hundred sheep.
Abu Dawud said: ‘Abbas transmitted this tradition in this way, but it is a misunderstanding.
