Silsilat al-Ahadith al-Sahihah

Sayyidah Umm al-‘Ala’ (may Allah be pleased with her) says: I was ill, and the Messenger of Allah (peace and blessings of Allah be upon him) came to visit me during my illness and said: “Umm al-‘Ala’! Rejoice, for Allah, because of a Muslim’s illness, removes his sins just as fire removes the impurities of gold and silver.”
