Musnad Abu Ya'la al-Mawsili 155:169

Abdullah ibn Umar ibn Aban narrated to us, Ismail ibn Ayyash narrated to us, he said: Abd al-Rahman ibn Amr al-Awza'i and Sa'id ibn Yusuf narrated to me, from Yahya ibn Abi Kathir, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) used to say in the prayer over the funeral: "O Allah, forgive our living and our dead, our present and our absent, our young and our old. O Allah, whoever among us You keep alive, then keep him alive upon Islam, and whoever among us You cause to die, then cause him to die upon faith. O Allah, do not deprive us of his reward, and do not lead us astray after him."
