Musannaf Ibn Abi Shaybah 31842 — What is said in supplication

Umayr bin Sa'id said: Sayyiduna Ali (may Allah be pleased with him) said four takbirs at the funeral of Yazid bin al-Mukaffaf. Then he stood at his grave and supplicated like this: "O Allah, this is Your servant and the son of Your servant. Today he has become Your guest, and You are the best of hosts. O Allah, make his grave spacious and forgive his sin. We know nothing but good, and You know better about this."
