Musannaf Ibn Abi Shaybah 3228 — Praying in a single garment

Sayyidah Asma' bint Abi Bakr (may Allah be pleased with them both) says: I saw my father praying in a single garment, so I said: Father, do you pray in a single garment while many of your garments are lying there? Sayyiduna Abu Bakr (may Allah be pleased with him) said: My daughter, the last prayer that the Messenger of Allah (peace and blessings be upon him) prayed behind me, he also prayed in a single garment.
