Musannaf Ibn Abi Shaybah 3220 — Praying in a single garment

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) says: Sayyiduna Ubayy bin Ka'b and Sayyiduna Ibn Mas'ud (may Allah be pleased with them both) differed about praying in a single garment. Sayyiduna Ubayy said that one garment is sufficient, while Sayyiduna Ibn Mas'ud said that two garments are necessary. Sayyiduna Umar (may Allah be pleased with him) came out to them, rebuked them both, and said: It grieves me greatly that the Companions of the Messenger of Allah (peace and blessings be upon him) should differ about one and the same thing. In that case, by whose fatwa of you two will the people act? As for the rest, Ibn Mas'ud wishes to avoid any deficiency in the prayer and is eager to attain its perfection; however, in my view the statement of Ubayy is the more preferable.
