Musannaf Ibn Abi Shaybah 12187 — Reports on burial at night

Musa bin Ali narrates from his father: I was with Sayyiduna Uqbah bin Amir (may Allah be pleased with him) when he was asked about the takbirs of the funeral prayer. He said: "Four." I said: "Are night and day the same (in this)?" He said: "Night and day are the same." I said: "May the deceased be buried at night?" He said: "Abu Bakr al-Siddiq (may Allah be pleased with him) was buried at night."
