It is narrated from Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "On the night of Mi'raj, I saw some men whose lips were being cut with scissors of fire. I said: 'O Jibreel! Who are these people?' He replied: 'These are the preachers of your ummah; they used to enjoin righteousness upon people but forgot themselves.'"
In Sharh al-Sunnah, al-Bayhaqi in Shu'ab al-Iman, and in their narration, it is mentioned: "They are the preachers of your ummah who used to say but did not do; they used to recite the Book of Allah but did not act upon it."
Hasan. Narrated in Sharh al-Sunnah and al-Bayhaqi in Shu'ab al-Iman.
