The funeral prayer Abu Hurayrah described when asked
He swore before answering the question.
اللَّهُمَّ إِنَّهُ عَبْدُكَ وَابْنُ عَبْدِكَ وَابْنُ أَمَتِكَ كَانَ يَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ وَأَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُولُكَ وَأَنْتَ أَعْلَمُ بِهِ اللَّهُمَّ إِنْ كَانَ مُحْسِنًا فَزِدْ فِي إِحْسَانِهِ وَإِنْ كَانَ مُسِيئًا فَتَجَاوَزْ عَنْ سَيِّئَاتِهِ
Allāhumma innahu ʿabduka wa-bnu ʿabdika wa-bnu amatik, kāna yashhadu an lā ilāha illā ant, wa anna Muḥammadan ʿabduka wa rasūluk, wa anta aʿlamu bih. Allāhumma in kāna muḥsinan fa-zid fī iḥsānih, wa in kāna musīʾan fa-tajāwaz ʿan sayyiʾātih
“O Allah, he is Your servant, son of Your servant, son of Your maidservant. He used to testify that there is no god but You and that Muhammad is Your servant and Messenger, and You know him better. O Allah, if he was a doer of good, add to his good. And if he was a wrongdoer, pass over his wrongs.”
Where this comes from
Someone asked Abu Hurayrah how he prayed over the dead. He answered by describing the whole thing: he follows from the family's house, and when the body is set down he says the takbir, praises Allah, sends peace on the Prophet, and then says this. It ends: do not deprive us of his reward, and do not put us to trial after him.
The full narration
Yahya related to me from Malik from Said ibn Abi Said al-Maqburi from his father that he had asked Abu Hurayra, "How do you pray over the dead?" and Abu Hurayra replied, "By the Life of Allah, I will tell you! I follow with the family and when the corpse is put down I say 'Allah is greater' and praise Allah and ask for blessings on His Prophet. Then I say, 'O Allah, he is Your slave and the son of Your male slave and Your female slave. He used to testify that there is no god but You and that Muhammad is Your slave and Your Messenger, and You know that best. O Allah, if he acted well, then increase for him his good action, and if he acted wrongly, then overlook his wrong actions. O Allah, do not deprive us of his reward, and do not try us after him.'" Allahumma inna huwa abduka wa'bnu abdika wa'bnu amatika. Kana yash-hadu an la ilaha illa ant wa anna Muhammadan abduka wa rasooluka, wa anta alamu bihi. Allahumma in kana muhsinan zid fi ihsanihi, wa in kana musiyan fa tajawaz an sayatihi. Allahumma la tahrimna ajrahu wa lataftina badahu
