“The Prophet (ﷺ) forbade throwing small pebbles and said:
‘They do not kill any game nor hurt the enemy, but they can break a
tooth or put out an eye.’” He did it again, and he (‘Abdullah)
said:
“I tell you that the Prophet (ﷺ) forbade that and then you
go and do
it again? I will never speak to you again.”
Sunan Ibn Majah Book 28, Hadith 27
