It was narrated by Ubaidullah ibn Ali Al-Halabi from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام that He said: "If you perform the funeral prayer for an enemy of Allah سبحانه وتعالى, the Exalted and Glorious, say: Allāhumma innā lā na‘lam minhu illā annahu ‘aduwwun laka wa lirasūlika. Allāhumma faḥsh qubrahu nāran wa uḥsh jawfahu nāran wa ‘ajjilhu ilā al-nār, fa-innahu kāna yuwālī a‘dā’aka wa yu‘ādī awliyā’aka wa yubghiḍu ahla bayti nabiyyika. Allāhumma ḍayyiq ‘alayhi qabrahu 'O’ Allah سبحانه وتعالى, we know of him only that he was an enemy to You and Your Messenger. O’ Allah سبحانه وتعالى, fill his grave with fire, fill his innermost with fire, and hasten him toward the fire, for he was loyal to Your enemies, hostile to Your allies, and had hatred for the family of Your Prophet. O’ Allah سبحانه وتعالى, make his grave tight upon him.'" And when his coffin bier is raised, say: Allāhumma lā tarfa‘hu wa lā tuzakkih "O’ Allah سبحانه وتعالى, do not raise him up or purify him." And if he However, if he is considered weak (Mustadh’af), say: Allāhumma ighfir lilladhīna tābū wa ittaba‘ū sabīlaka wa qihim ‘adhāba al-jaḥīm "O’ Allah سبحانه وتعالى, forgive those who repent, follow Your way, and protect them from the torment of Hell." If you are unaware of his condition, then say: Allāhumma in kāna yuḥibbu al-khayra wa ahlahu faghfir lahu wa irḥamhu wa tajāwaz ‘anhu "O’ Allah سبحانه وتعالى, if he loved good and its people, forgive him, have mercy upon him, and overlook him." And If the Mustadh’af has a connection to you, seek forgiveness for him as an intercession but not as an expression of loyalty."
