‘A’isha said that when his family were exhausted by fever God’s messenger ordered some hasa’* to be prepared and then ordered them to sip some of it; and he used to say, “It heartens the sad and clears the heart of the invalid as one of you clears dirt away from her face with water.” *A kind of soap made of flour, water and either oil or clarified butter. Tirmidhi transmitted it, saying this is a hasan sahih tradition.
