Aishah narrated:
"Whenever one of the wives of the Messenger of Allah (s.a.w) became (feverishly) ill, he would order that some broth be prepared. Then he would tell them to take some of the broth. And he would say: 'It firms the heart of the grieved, and it rids the worries from the heart of the ill just as one of you removes dirt from her face with water."
