Musnad Ahmad 969:1

Abu Abd al-Rahman—meaning al-Muqri—narrated to us, Sa’id—meaning Ibn Abi Ayyub—narrated to us, Abu ‘Isa al-Khurasani narrated to me, from ‘Abdullah ibn al-Qasim, who said: A neighbor of the Prophet, may Allah bless him and grant him peace, narrated to me that she used to hear the Messenger of Allah, may Allah bless him and grant him peace, saying at the break of dawn: "O Allah, I seek refuge in You from the punishment of the grave, and from the trial of the grave." Abu ‘Isa said: So I said to ‘Abdullah: "Have you considered if a person combines them?" He said: He said that the Messenger of Allah, may Allah bless him and grant him peace, said: "Whatever he said."
