Musnad Abu Ya'la al-Mawsili 129:122

Zuhayr narrated to us, Yazid informed us, Humayd informed us, from Anas, who said: When the Messenger of Allah (may Allah bless him and grant him peace) returned from the expedition of Tabuk and drew near to Medina, he said: "Indeed, there are people in Medina who, you did not travel any distance nor cross any valley, except that they were with you in it." They said: "O Messenger of Allah, even though they were in Medina?" He said: "Yes, the excuse detained them."
