Sayyiduna Afif bin Ma'dikarib (may Allah be pleased with him) said: We were with the Messenger of Allah (peace and blessings be upon him) when Imru' al-Qays was mentioned, and the Messenger of Allah (peace and blessings be upon him) said: "That is a man who is remembered in this world and forgotten in the Hereafter, honoured in this world and obscure in the Hereafter. He will come on the Day of Resurrection holding the banner of the poets in his hand, leading them to the Fire."
