Yahya related to me from Malik from Yahya ibn Said that death
came to a man in the time of the Messenger of Allah, may Allah bless
him and grant him peace. A man said, "He was fortunate," as he had
died without being tried by illness. The Messenger of Allah, may Allah
bless him and grant him peace, said, "Alas for you, what will let you
know that if Allah had tried him with illness, He would have wiped out
his wrong actions."
Muwatta Malik Book 50, Hadith 8
