Musnad Abu Ya'la al-Mawsili 155:213

Zuhayr ibn Harb narrated to us, Isma'il ibn Ibrahim narrated to us, Ayyub narrated to us, from Muhammad, from Abu Hurayrah, who said: A man called out to the Messenger of Allah (may Allah bless him and grant him peace), "Should one of us pray in a single garment?" He said, "When Allah has made it abundant for you, then be abundant with yourselves. A man may gather his garments upon himself. A man may pray in an izar (waist-wrapper) and a rida (upper garment), in an izar and a qamis (shirt), in sirwal (trousers) and a qaba (outer garment), in sirwal and a rida, in a tubban (short drawers) and a qaba." He said, "And I think he said: in a tubban and a rida."
