Musannaf Ibn Abi Shaybah 31841 — What is said in supplication

Abdullah bin Abi Bakr said: When earth had been poured over the grave of a deceased person and it had been levelled, Sayyiduna Anas (may Allah be pleased with him) would stand over the grave and supplicate like this: "O Allah, Your servant has been returned to You, so be kind to him and have mercy on him. O Allah, make the earth spacious at his sides, open the gates of heaven for his soul, and accept him from Yourself with a goodly acceptance. O Allah, if he was a doer of good, then double his good deeds; and if he was a wrongdoer, then overlook his wrongs."
