“May Allah make your illness a means for wiping out your sins because there is no reward for sickness but that it erases sins and makes them fall like (dried) leaves. Reward lies in saying by the tongue and doing something with the limbs. Certainly, Allah, the Glorified One, admits into Paradise by virtue of truthfulness of intention and chastity of heart whomsoever He wishes from among His servants.”
