The Prophet ﷺ forbade the throwing of stones (with the thumb and the index or middle finger), and said "It neither hunts a game nor kills (or hurts) an enemy, but it gouges out an eye or breaks a tooth."  

نَهَى النَّبِيُّ ﷺ عَنِ الْخَذْفِ وَقَالَ إِنَّهُ لاَ يَقْتُلُ الصَّيْدَ وَلاَ يَنْكَأُ الْعَدُوَّ وَإِنَّهُ يَفْقَأُ الْعَيْنَ وَيَكْسِرُ السِّنَّ  

It neither inflicts defeat to the enemy nor kills the game but breaks the tooth and puts the eye out. This hadith has been transmitted on the authority of Ibn Mahdi with a slight variation of wording.  

نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْخَذْفِ قَالَ ابْنُ جَعْفَرٍ فِي حَدِيثِهِ وَقَالَ إِنَّهُ لاَ يَنْكَأُ الْعَدُوَّ وَلاَ يَقْتُلُ الصَّيْدَ وَلَكِنَّهُ يَكْسِرُ السِّنَّ وَيَفْقَأُ الْعَيْنَ وَقَالَ ابْنُ مَهْدِيٍّ إِنَّهَا لاَ تَنْكَأُ الْعَدُوَّ وَلَمْ يَذْكُرْ تَفْقَأُ الْعَيْنَ  

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.  

نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْخَذْفِ قَالَ إِنَّهُ لاَ يَصِيدُ صَيْدًا وَلاَ يَنْكَأُ عَدُوًّا وَإِنَّمَا يَفْقَأُ الْعَيْنَ وَيَكْسِرُ السِّنَّ  

“The Prophet ﷺ forbade throwing small pebbles and said: ‘They do not kill any game or hurt the enemy, but they can break a tooth or put out an eye.’”  

نَهَى النَّبِيُّ ﷺ عَنِ الْخَذْفِ وَقَالَ إِنَّهَا لاَ تَقْتُلُ الصَّيْدَ وَلاَ تَنْكِي الْعَدُوَّ وَلَكِنَّهَا تَفْقَأُ الْعَيْنَ وَتَكْسِرُ السِّنَّ  

[Machine] The Messenger of Allah ﷺ forbade stone-throwing and said, "By it, neither an enemy is wounded nor a hunt captured."  

نَهَى رَسُولُ اللهِ ﷺ عَنِ الْخَذْفِ وَقَالَ إِنَّهَا لَا يُنْكَأُ بِهَا عَدُوٌّ وَلَا يُصَادُ بِهَا صَيْدٌ  

"لا تَخْذِفُوا فَإِنَّهُ لا يُصَادُ بِهِ الصَّيدُ، وَلا يُنْكَأُ الْعَدُوُّ، وَيَكْسِرُ السِّنَّ، وَيفقَأُ العَينَ".
