It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "At the end of time there will emerge people who are young in age and immature in intellect. They will speak (apparently) the best of words, and they will recite the Noble Qur'an, but it will not go beyond their throats. They will pass out of the religion of Islam just as an arrow passes through the game. So whoever encounters them should fight them, for killing them is a cause of reward with Allah Almighty for the one who kills them."
