Sunan an-Nasai Book 1, Hadith 62

أَخْبَرَنِي هَارُونُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا مَعْنٌ، قَالَ حَدَّثَنَا مُعَاوِيَةُ بْنُ صَالِحٍ، عَنْ حَبِيبِ بْنِ عُبَيْدٍ، عَنْ جُبَيْرِ بْنِ نُفَيْرٍ، قَالَ شَهِدْتُ عَوْفَ بْنَ مَالِكٍ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يُصَلِّي عَلَى مَيِّتٍ فَسَمِعْتُ مِنْ دُعَائِهِ وَهُوَ يَقُولُ ‏ "‏ اللَّهُمَّ اغْفِرْ لَهُ وَارْحَمْهُ وَعَافِهِ وَاعْفُ عَنْهُ وَأَكْرِمْ نُزُلَهُ وَأَوْسِعْ مُدْخَلَهُ وَاغْسِلْهُ بِالْمَاءِ وَالثَّلْجِ وَالْبَرَدِ وَنَقِّهِ مِنَ الْخَطَايَا كَمَا يُنَقَّى الثَّوْبُ الأَبْيَضُ مِنَ الدَّنَسِ ‏"‏ ‏.‏

Awf bin Malik said:"I heard the Messenger of Allah (ﷺ) offering the (funeral) prayer for one who had died, and I heard him say in his supplication: 'Allahummaghfir lahu warhamhu wa 'afihi was a'fu 'anhu, wa akrim nuzulahu wa wassi' ,adkhalahu waghsilhu bil-ma'i wath-thalji wal-baradi wa naqqihi min al-khataya kama ynaqqath-thawb al-abyad min ad-danas. (O Allah, forgive him and have mercy on him, keep him safe and sound and forgive him, honor the place where he settles and make his entrance wide; wash him with water and snow and hail, and cleanse him of sin as a white garment is cleansed of dirt)
