Musannaf Ibn Abi Shaybah 31839 — What a man says in supplication when

Jubayr bin Adi said: I was informed that Sayyiduna Ali (may Allah be pleased with him) used to recite this supplication when a deceased person was placed in the grave: "In the name of Allah, and upon the way of the Messenger of Allah (peace and blessings be upon him), affirming the truth of Your Book and Your Messengers, and with certainty in the resurrection after death. O Allah, make his grave spacious for him and give him the glad tidings of Paradise."
