from his father who said: "When the Messenger of Allah would perform the Salat for the funeral he would said: (Allahammaghfir li-hayyina wa mayyittina, wa shahidina wa gha'ibina, wa saghirina wa kabirina, wa dhakarina wa unthana) 'O Allah! Forgive our living and our deceased, our present and our absent, our young and our old, our male and our female.'"  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى عَلَى الْجَنَازَةِ قَالَ اللَّهُمَّ اغْفِرْ لِحَيِّنَا وَمَيِّتِنَا وَشَاهِدِنَا وَغَائِبِنَا وَصَغِيرِنَا وَكَبِيرِنَا وَذَكَرِنَا وَأُنْثَانَا قَالَ يَحْيَى وَحَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ مِثْلَ ذَلِكَ وَزَادَ فِيهِ اللَّهُمَّ مَنْ أَحْيَيْتَهُ مِنَّا فَأَحْيِهِ عَلَى الإِسْلاَمِ وَمَنْ تَوَفَّيْتَهُ مِنَّا فَتَوَفَّهُ عَلَى الإِيمَانِ قَالَ وَفِي الْبَابِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَعَائِشَةَ وَأَبِي قَتَادَةَ وَعَوْفِ بْنِ مَالِكٍ وَجَابِرٍ  

"I heard the Messenger of Allah, while he was performing Salat for a deceased person. I could hear him saying in his prayer: (Allahummagfir lahu, war hamhu, waghsilhu bil-baradi (waghsilhu) kama yughsaluth-thawb) 'O Allah! Forgive him, have mercy upon him, and wash him with (snow or ice) (and wash him) just as a garment is washed.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يُصَلِّي عَلَى مَيِّتٍ فَفَهِمْتُ مِنْ صَلاَتِهِ عَلَيْهِ اللَّهُمَّ اغْفِرْ لَهُ وَارْحَمْهُ وَاغْسِلْهُ بِالْبَرَدِ وَاغْسِلْهُ كَمَا يُغْسَلُ الثَّوْبُ
