Yahya related to me from Malik from Hisham ibn Urwa from his
father that Umar ibn Abi Salama saw the Messenger of Allah, may Allah
bless him and grant him peace, praying in one garment in the house of
Umm Salama. He was completely covered by it, and had put both ends
over his shoulders.
Muwatta Malik Book 8, Hadith 30
