At the end of time, there will come a people, young in age and foolish in mind. They will speak about the best words of creation, but they will pass through Islam as an arrow passes through its target

The Commander of the Believers, ‘Ali ibn Abi Tālib (may Allah be pleased with him), informed that if you heard me narrating from the Prophet (may Allah's peace and blessings be upon him), I neither use figurative language, nor allusions, nor ambiguous statements; rather, I speak clearly. If I fall from the sky, it would be easier and lighter than to narrate from the Messenger of Allah (may Allah's peace and blessings be upon him) while attributing lies to him.

However, if I spoke about matters between myself and the people, then war is deception, and I may use figurative language, allusions, or double-meaning statements. Indeed, I heard the Prophet (may Allah's peace and blessings be upon him) say: At the end of time, there will come youth, young in age and weak in intellect. They will quote words from the Qur’an and recite them frequently, but they will leave Islam and transgress its bounds just as an arrow passes through its target.

Their faith will not go beyond their throats. Wherever you encounter them, kill them, for killing them will bring a reward for those who kill them on the Day of Judgment.
