a woman threw some pebbles and stuck another woman, and she miscarried. The Messenger of Allah stipulated (a Diyah of ) fifty sheep for her child. And on that day, he forbade throwing pebbles.
Sunan an-Nasa'i Book 45, Hadith 108
← Previous Hadith a Mukatab was killed at the time of the Messenger of Allah and he commanded that the Diyah be paid (equivalent) to the Diyah for a free man, (proportionate to the amount he had paid off towards buying his freedom).

Sunan an-Nasa'i Book 45, Hadith 107 Next Hadith → a woman threw pebbles at another woman and the woman who was struck miscarried. The matter was referred to the prophet and he set the blood money for her child at five hundred sheep. And on that day, he forbade throwing pebbles. (Sahih) Abu 'Abdur-Rahman (An-Nasa'i) said: This is an error, and it must be that the intent was one hundred camels. And the prohibition of throwing pebbles has been related from 'Abdullah bin Buraidah, from 'Abdullah bin Mughaffal.
