Hadith.500 - Salim ibn Mukram narrated from Imam Jafar ibn Muhammad Al-Sadiq (as) that He said: "A pillow of earth should be placed for the deceased, and a clump of soil behind their back to prevent them from lying flat. The knots of their shroud should be untied, their face uncovered, and supplications should be made: Allāhumma ‘abduka wa ibnu ‘abdika wa ibnu amatika nazala bika wa anta khayru manzūlin bih. Allāhumma ifsaḥ lahu fī qabrihi wa laqqinh ḥujjatahu wa alḥiqhu binabiyyihi wa qihi sharra Munkarin wa Nakīr 'O’ Allah (swt), this is Your servant, the child of Your servant and maidservant. They have returned to You, and You are the best to receive. O’ Allah (swt), expand their grave for them, teach them their proof, and join them with their Prophet. Protect them from the trial of Munkar and Nakir.'" Then, place your right hand under their right shoulder and your left hand on their left shoulder, and shake them firmly while saying: Yā Fulān ibn Fulān, Allāhu rabbuka, wa Muḥammadun nabiyyuka, wa al-Islāmu dīnuka, wa ‘Aliyyun walīyuka wa imāmuka "O’ [name of the deceased], child of [father’s name], Allah (swt) is your Lord (azj), Muhammad is your Prophet, Islam is your religion, Ali is your guardian and Imam" - Name each of the Imams, ending with: 'Your Imams are the guides and the righteous.' Then repeat the talqeen (prompting of faith) once more. And when you put earth over him or when placing bricks over the grave, say: Allāhumma irḥam ghurbatahu wa ṣil waḥdatahu wa ānis waḥshatahu wa āmin raw‘atahu wa askin ilayhi min raḥmatika raḥmatan yastaghnī bihā ‘an raḥmati man siwāk, wa uḥshuruhu ma‘a man kāna yatawallāh "O’ Allah (swt), have mercy on their loneliness, connect their solitude, comfort their fear, and fill them with Your mercy so that they need no mercy from anyone other than You. Unite them with those they loved." When visiting their grave, recite this supplication facing the Qibla, with hands on the grave. Upon exiting the grave, while brushing the dirt off your hands, say: Innā lillāhi wa innā ilayhi rāji‘ūn "Indeed, we belong to Allah (swt), and indeed, to Him we shall return." Throw dirt onto the grave with the backs of your hands three times, saying: Allāhumma īmānan bika wa taṣdīqan bikitābika, hādhā mā wa‘adanā Allāhu wa rasūluhu wa ṣadaqa Allāhu wa rasūluhu "O’ Allah (swt), we believe in You and affirm Your Book. This is what You and Your Messenger have promised, and Allah (swt) and His Messenger have spoken the truth." Whoever performs this and says these words will earn a reward for every particle of soil. Once the grave is made/leveled, pour water over it, beginning at the head and circling around all four sides, returning to the head without breaking the flow of water. If any water remains, pour it in the middle of the grave. Place your hand on the grave, supplicate for the deceased, and seek forgiveness for them.
