Kathir bin Mudrik (may Allah have mercy on him) says that when Sayyiduna Umar (may Allah be pleased with him) levelled the earth over a deceased person, he would say: "Allahumma aslamahu ilayka al-ahlu wal-malu wal-ashiratu, wa dhanbuhu azimun, faghfir lahu" (O Allah, his family, wealth and kin have handed him over to You, and his sins are great, so forgive him).
