If a person, who is used to fasting the six days of Shawwal regularly, becomes sick, hindered, or feels lazy to fast them in one of the years, is this a sin?
(Part No. 10; Page No. 392) We hear that anyone who fasts them regularly should not give up doing so.
Fasting the Six Days of Shawwal after the day of `Eid-ul-Fitr (the Festival of Breaking the Fast) is an act of Sunnah (whatever is reported from the Prophet). It is not obligatory upon anyone who fasts them once or more to continually fast them. It is not a sin to abstain from fasting them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
