O Allah, forgive those of us who are living and those of us who are dead, those of us who are young and those who are old, those of us who are males and those who are females, and those of us who are present and those who are absent. O Allah, whoever of us You give life, let him live upon Islam, and whoever of us You take in death, let him die in a state of faith. O Allah, deprive us not of his reward, and subject us not to temptation after his death

عن أَبي هريرة وأبي قتادة وَأبي إبراهيم الأشهلي عن أبيه -وأبوه صَحَابيٌّ- رضي الله عنهم عن النبيِّ صلى الله عليه وسلم أنه صلى على جِنَازَةٍ، فقال: «اللهم اغفر لِحَيِّنَا ومَيِّتِنَا، وصغيرنا وكبيرنا، وذَكرنا وأُنثانا، وشَاهِدِنَا وغَائِبِنَا، اللهم مَنْ أَحْيَيْتَهُ مِنَّا فَأَحْيِهِ على الإسلامِ، ومَنْ تَوَفَّيْتَهُ مِنَّا فَتَوَفِّهِ على الإيمانِ، اللهم لا تَحْرِمْنَا أَجْرَهُ، ولا تَفْتِنَّا بَعْدَهُ».

Abu Hurayrah, Abu Qatādah, and Abu Ibrahīm al-Ash'hali - from his father (who was a Companion) - reported that the Prophet (may Allah's peace and blessings be upon him) once offered the funeral prayer over a deceased person and said the following: "O Allah, forgive those of us who are living and those of us who are dead, those of us who are young and those who are old, those of us who are males and those who are females, and those of us who are present and those who are absent. O Allah, whoever of us You give life, let him live upon Islam, and whoever of us You take in death, let him die in a state of faith. O Allah, deprive us not of his reward, and subject us not to temptation after his death."
