Dua 1
اَللّٰهُمَّ اغْفِرْ لَهٗ وَارْحَمْهُ وَعَافِهٖ وَاعْفُ عَنْهُ وَاَكْرِمْ نُزُلَهٗ وَوَسِّعْ مُدْخَلَهٗ وَاغْسِلْهُ بِالْمَآءِ وَالثَّلْجِ وَالْبَرَدِ وَنَقِّهٖ مِنَ الْخَطَايَا كَمَا نَقَّيْتَ الثَّوْبَ الْاَبْيَضَ مِنَ الدَّنَسِ وَاَبْدِلْهُ دَارًا خَيْرًا مِّنْ دَارِهٖ وَاَهْلًا خَيْرًا مِّنْ اَهْلِهٖ وَزَوْجًا خَيْرًا مِّنْ زَوْجِهٖ وَاَدْخِلْهُ الْجَنَّةَ وَاَعِذْهُ مِنْ عَذَابِ الْقَبْرِ [وَمِنْ عَذَابِ النَّارِ]
O Allah! Forgive him, have mercy on him, grant him well-being and pardon him. Make his hospitality honourable and make his grave spacious, and wash away his sins with water, snow and hail. Cleanse him of sins as You have cleansed the white garment of dirt. Give him in exchange a home better than his home, a family better than his family and a wife better than his wife. Admit him to Paradise and protect him from the punishment of the grave and the punishment of the Fire.
Sahih Muslim, no. (963), the wording is his, Sunan Ibn Majah, no. (1500), as-Sunan al-Kubra of an-Nasa'i, no. (1983), and the words in square brackets are in both of them; it is also in Muslim, but with doubt, Sunan at-Tirmidhi, no. (1025).
