Asma bint Abu Bakr reported,

A woman suffering from fever would be brought to her, and she would call for water and pour it into the opening of the woman's garment, saying that the Messenger of Allah ﷺ said, "Cool it with water," and he said, "It comes from the heat of Hell."In Ibn Numayr's version, she poured the water between the woman and the opening of her garment. In Abu Usama's version, the words "It comes from the heat of Hell" are not mentioned.Abu Ahmad said that Ibrahim said, Hasan bin Bishr narrated to us, Abu Usama narrated to us with this chain of transmission.
