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. (Using translation from Nasāʾī 4814)  

أَنَّ امْرَأَةً خَذَفَتِ امْرَأَةً فَأَسْقَطَتِ الْمَخْذُوفَةُ فَرُفِعَ ذَلِكَ إِلَى النَّبِيِّ ﷺ «فَجَعَلَ عَقْلَ وَلَدِهَا خَمْسَمِائَةٍ مِنَ الْغَنَمِ وَنَهَى يَوْمَئِذٍ عَنِ الْخَذْفِ» قَالَ لَنَا أَبُو عَبْدِ الرَّحْمَنِ هَذَا وَهْمٌ وَيَنْبَغِي أَنْ يَكُونَ أَرَادَ مِائَةً مِنَ الْغَنَمِ وَقَدْ رُوِيَ النَّهْيُ عَنِ الْخَذْفِ عَنْ عَبْدِ اللهِ بْنِ بُرَيْدَةَ عَنْ عَبْدِ اللهِ بْنِ مُغَفَّلٍ
