Mishkat al-Masabih #3392

‘Ali told that he heard God’s Messenger say, “In the last time people will come forth, young and foolish, speaking the finest words men speak, but their faith will not pass their throats. They will come out from the religion as an arrow does from the animal it is aimed at. Wherever you meet them kill them, for a reward for killing them will be given on the day of resurrection to those who kill them.” (Bukhari and Muslim.)
