It is narrated from Sayyiduna Anas (may Allah be pleased with him): "The Prophet (peace and blessings be upon him) had a wrap dyed with wars and saffron. He (peace and blessings be upon him) would wear it when going round to his pure wives. So when it was the night of one of them, she would sprinkle it with water, and when it was the night of another, she too would sprinkle it with water."
No one narrated this hadith from Thabit (may Allah have mercy on him) except Umarah (may Allah have mercy on him), and Mu'ammal (may Allah have mercy on him) is alone in narrating it.
