The ruling on leaving off a person’s customary voluntary fasting

Question:
May Allah reward you. The questioner says: I have been fasting fifteen consecutive days in the month of Sha'ban as a voluntary act for the past four years. If I leave off fasting this year because I am unable to fast, is there anything required of me?

Answer:
There is nothing required of you, because fasting in Sha'ban is a recommended practice (sunnah). Whoever does it earns a reward, and whoever leaves it off commits no sin. You mentioned that you are excused because you are ill. We hope that Allah will record a reward for you, because you did not leave off fasting except for an excuse. If a person who is excused performs a righteous deed while he is healthy, and then becomes ill and leaves it off because of the illness, Allah records for him the reward he would have earned had he been healthy.
