Musannaf Ibn Abi Shaybah 32693 — Reports on talk about rulers

Ubadah bin Nusayy said: The Companions (may Allah be pleased with them) mentioned the poets before the Prophet (peace and blessings be upon him). When Imru' al-Qays was mentioned, he said: "This poet's mention will remain on people's tongues in this world and on people's tongues in the Hereafter, and on the Day of Resurrection he will be carrying the banner of poetry in Hell," or he said: "He will be carrying the banner of poetry in the Fire."
