Anas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "On the night of Mi'raj, I passed by some people whose lips were being cut with scissors of fire. I asked: 'O Jibreel! Who are these people?' He replied: 'These are the preachers of your Ummah whose words and actions were contradictory.'" (Tirmidhi), and he said: This hadith is gharib. Hasan, narrated by Tirmidhi.
