‘Abd b. Mughaffal said:

The Messenger of Allah ﷺ prohibited throwing pebbles (in sport) saying : game is not caught by such means. Neither is an enemy injured, but it may sometimes put out an eye or break a tooth.

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ عُقْبَةَ بْنِ صُهْبَانَ، عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ، قَالَ نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْخَذْفِ قَالَ
" إِنَّهُ لاَ يَصِيدُ صَيْدًا وَلاَ يَنْكَأُ عَدُوًّا وَإِنَّمَا يَفْقَأُ الْعَيْنَ وَيَكْسِرُ السِّنَّ " .
