It was narrated from 'Abdullah bin Buraidah, from his father, that: 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.
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، وَإِبْرَاهِيمُ بْنُ يُونُسَ بْنِ مُحَمَّدٍ، قَالاَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، قَالَ حَدَّثَنَا يُوسُفُ بْنُ صُهَيْبٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، أَنَّ امْرَأَةً، خَذَفَتِ امْرَأَةً فَأَسْقَطَتْ فَجَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي وَلَدِهَا خَمْسِينَ شَاةً وَنَهَى يَوْمَئِذٍ عَنِ الْخَذْفِ . أَرْسَلَهُ أَبُو نُعَيْمٍ .
