Hadith 17:766
Mu'tamir narrated to us, from Ma'mar, from al-Zuhri, that the Prophet, peace and blessings of Allah be upon him, did not say anything of poetry except that it had been said before him, except for this: "This is the porter, not the porter of Khaybar; this is more pious than our Lord, and purer."
حدثنا معتمر عن معمر عن الزهري أن النبي صلى الله عليه وسلم لم يقل شيئا من الشعر إلا قد قيل قبله إلا هذا % هذا الحمال لا حمال خيبر % هذا أبر ربنا وأطهر %
