Q. Alot of people say that we cannot keep the shawwal fasts from the 2nd of Shawaal as Eid is for 3 days, please advise?
A. It is forbidden to fast on five days in the Islamic calendar i.e. Eid-ul-Fitr (the first of Shawwal), Eid-ul-Adha (the tenth of Zul-Hijjah) and the three days of Tashreeq (three days after Eid-ul-Adha-11-12-13 of Zul-Hijjah). (Al Ikhtiyaar Li Ta’leelil Mukhtaar 1/125)
The prohibition of fasting on the three days of Tashreeq (three days after Eid-ul-Adha-11-12-13 of Zul-Hijjah) refers to fasting three days after Eid-ul-Adha (the tenth of Zul-Hijjah). It does not refer to fasting three days after Eid-ul-Fitr (the first of Shawwal). Hence, it is permissible to fast immediately after Eid-ul-Fitr (the first of Shawwal) even if it is three days after Eid-ul-Fitr (the first of Shawwal).
