Musnad Ahmad 1153:412

Ibrahim ibn Abi al-Abbas narrated to us, he said: Sharik informed us, from Asim ibn Ubayd Allah, from Abdullah ibn Amir ibn Rabi'ah, from Aisha, she said: I missed him during the night, and behold, he was at al-Baqi'. He said: "Peace be upon you, abode of a believing people. You are our predecessors, and we are joining you. O Allah, do not deprive us of their reward, and do not try us after them." She meant the Prophet, may Allah bless him and grant him peace.
