“The Messenger of Allah (ﷺ) offered the funeral prayer for a man among the Muslims and I heard him say: ‘O Allah, so-and-so the son of so-and-so is in Your case and under Your protection. Protect him from the trial of the grave and the torment of the Fire, for You are the One Who keeps the promise and You are the Truth. Forgive him and have mercy on him, for You are the Oft-Forgiving, Most Merciful.”
Sunan Ibn Majah Book 6, Hadith 67
← Previous Hadith “When the Messenger of Allah (ﷺ) offered the funeral prayer he would say: ‘Allahummaghfir lihayyina wa mayyitina, wa shahidina wa gha’ibina, wa saghirina wa kabirina, wa dhakarina wa unthana. Allahumma man ahyaitahu minna fa'ahyihi ‘alal-Islam, wa man tawaffaytahu minna fa tawaffahu ‘alal- iman. Allahumma la tahrimna ajrahu wa la tudillana ba’dah. [O Allah, forgive our living and our dead, those who are present and those who are absent, our young and our old, our males and our females. O Allah, whomever of us You cause to live, let him live in Islam, and whomever of us You cause to die, let him die in (a state of) faith. O Allah, do not deprive us of his reward, and do not let us go astray after him].’”

Sunan Ibn Majah Book 6, Hadith 66 Next Hadith → “I saw the Messenger of Allah (ﷺ) offering the funeral prayer for a man among the Ansar, and I heard him say: ‘Allahumma salli ‘alayhi waghfirlahu warhamhu, wa ‘afihi wa’fu ‘anhu, waghsilhu bi ma’in wa thaljin wa baradin, wa naqqihi min adh-dhunubi wal-khataya kama yunaqqath-thawbul-abyadu minad-danas, wa abdilhu bi darihi daran khayran min darihi, wa ahlan khayran min ahlili, wa qihi fitnatal-qabri wa ‘adhaban-nar. (O Allah, send blessing upon him, forgive him, have mercy on him, keep him safe and sound, and pardon him; wash him with water and snow and hail, and cleanse him of sins just as a white garment is cleansed of dirt. Give him in exchange for his house that is better than his house, and a family that is better than his family. Protect him from the trial of the grave and the torment of the Fire).’”
