Musannaf Ibn Abi Shayba 21:657

Abu Usama narrated to us, he said: Hisham al-Dastawa'i narrated to us, from Yahya ibn Abi Kathir, from Abu Ibrahim al-Ansari, from his father, that he heard the Messenger of Allah (may Allah bless him and grant him peace) in the funeral prayer: "O Allah, forgive our living and our dead, our present and our absent, our male and our female, and our young and our old."
