Musannaf Ibn Abi Shayba 27:803

Muhammad ibn Fudayl narrated to us, from al-Ajalih, from Abdullah ibn Sharik, from Jundub al-Azdi, who said: We went out with Salman to al-Hira. He turned toward Kufa and said: "The dome of Islam. There is no settlement from which is warded off what is warded off from these settlements. Muhammad, may Allah bless him and grant him peace, was in it." "And the world will not pass away until every believer gathers in it, or a man whose desire is toward it."
