Musnad Abu Ya'la al-Mawsili 150:89

Muhammad ibn al-Sabbah al-Bazzar narrated to us, Sharik narrated to us, from Asim ibn Ubayd Allah, from Abdullah ibn Amir, from Aisha, who said: I missed the Messenger of Allah (peace and blessings of Allah be upon him), so I followed him. He came to al-Baqi and said: "Peace be upon you, O abode of a believing people. You are our predecessors, and we are, by Allah, following you. O Allah, do not deprive us of their reward, and do not try us after them."
