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.

(The clerk of Al-Mughira) Muawiya wrote to Al-Mughira 'Write to me what you have heard from Allah's Apostle.' So he (Al-Mughira) wrote to him: Allah's Prophet used to say at the end of each prayer: "La ilaha illalla-h wahdahu la sharika lahu, lahul Mulku, wa lahul Hamdu wa hula ala kulli shai'in qadir. 'Allahumma la mani' a lima a'taita, wala mu'tiya lima mana'ta, wala yanfa'u dhuljadd minkal-jadd." He also wrote to him that the Prophet used to forbid (1) Qil and Qal (idle useless talk or that you talk too much about others), (2) Asking too many questions (in disputed Religious matters); (3) And wasting one's wealth by extravagance; (4) and to be undutiful to one's mother (5) and to bury the daughters alive (6) and to prevent your favors (benevolence to others (i.e. not to pay the rights of others (7) And asking others for something (except when it is unavoidable).

The Prophet said "The most superior way of asking for forgiveness from Allah is: O Allah, You are my Lord, there is none worthy of worship except You. You have created me, and I am Your servant, and I am faithful to Your covenant and promise as much as I can. I seek refuge in You from the evil of what I have done. I acknowledge Your blessings upon me, and I admit my sins. So forgive me, for none forgives sins except You.
(Allahumma anta Rabbi la ilaha illa anta, Khalaqtani wa ana `Abduka, wa ana `ala `ahdika wa wa`dika mastata`tu, A`udhu bika min Sharri ma sana`tu, abu'u Laka bini`matika `alaiya, wa abu'u laka bidhanbi faghfir lee fa innahu la yaghfiru adhdhunuba illa anta) "
The Prophet added. "If somebody recites it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise."
