Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated ‘Abdullah bin Mughaffal Al-Muzani (Radi-Allahu ‘anhu):
The Prophet (Sallallahu ‘Alaihi Wa Sallam) 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.”
