Sunan Abi Dawud, Hadith 5250 ⓘ
‘Abd b. Mughaffal said : The Messenger of Allah 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 صلى الله عليه وسلم عَنِ الْخَذْفِ قَالَ " إِنَّهُ لاَ يَصِيدُ صَيْدًا وَلاَ يَنْكَأُ عَدُوًّا وَإِنَّمَا يَفْقَأُ الْعَيْنَ وَيَكْسِرُ السِّنَّ " .
