Musannaf Ibn Abi Shaybah 6337 — Praying in a single garment

Sayyiduna Abu Umamah (may Allah be pleased with him) was asked about praying in a single shirt, and he said: There is no harm in it. Then he was asked about praying in a raytah (a soft, thin cloth), and he said: If one brings the cloth out from under the right armpit and puts it over the left shoulder, then there is no harm in that either.
