Fasting Six Days of Shawwal

All praise is due to Allah The Exalted, and may Allah raise the rank of our beloved Prophet Muhammad peace be upon him, his kind relatives and companions, and protect his nation from that which he feared for them thereafter;

It is highly recommended to fast six days of the month of Shawwal, as this is a praiseworthy act which results in abundant reward. However, it is not required to fast six days continuously without any interruption. One can fast according to convenience any time during the month.

The Prophet (peace and blessings be upon him) is reported to have said, “Whoever fasts the month of Ramadan, and then follows it up by (fasting) six days of Shawwal, it is as though he has fasted the whole year.” (narrated by Imam Muslim)

However, there are other scholars who do not consider it absolutely necessary to begin the optional fasting of six days of Shawwal immediately after `Eid Al-Fitr. According to them, one may fast any of the six days of Shawwal. Neither do they consider it necessary for a person to fast the six days consecutively. So long as one has fasted six days either consecutively or separately, he has fulfilled the requirement and he will receive the same rewards.

We humbly ask Allah to enlighten us with the light of Knowledge, and keep us steadfast to the path of truth and righteousness.

Ameen.
