Sayyiduna Abdullah bin Abdullah bin al-Mughirah al-Makhzumi (may Allah be pleased with him) states: I saw the Prophet (peace and blessings be upon him) praying in a single garment in the house of his honoured wife, Sayyidah Umm Salamah (may Allah be pleased with her), and he had no other garment on his body besides it.
Imam Ahmad recorded this narration, and mentioned that he (peace and blessings be upon him) had crossed the two ends of that garment over opposite sides; he mentioned this in another narration. The narrators of this narration are thiqat (trustworthy).
