Musannaf Ibn Abi Shaybah

Hazrat Ziyad bin Jubair narrates that a man came to Hazrat Abdullah bin Umar (may Allah be pleased with them) and asked: A person has made a vow to fast for one day, but if that day falls on Eid al-Fitr or Eid al-Adha, then what should he do? Hazrat Ibn Umar (may Allah be pleased with them) replied: Allah Almighty has commanded the fulfillment of vows, and the Noble Prophet (peace and blessings be upon him) has forbidden fasting on these days.

Hasan was asked that a person has made a vow to fast on Mondays and Thursdays, but if Eid al-Fitr or Eid al-Adha falls on those days, what should he do? He replied that he should not fast on those days and should make up for it on other days.

Ibrahim says: In compensation, he will fast another day and will offer its expiation.

Hazrat Shu’bah narrates from his maternal aunt that she had vowed to fast every Friday. Then, on that day, Eid al-Fitr or Eid al-Adha occurred. She asked Hazrat Jabir bin Zaid about this. He said: Feed a poor person.

Hazrat Sha’bah says that I asked Hazrat Hakam and Hazrat Hammad: A woman has made a vow that she will fast every Friday; what if Eid al-Fitr or Eid al-Adha falls on that day? Both of them replied: She should fast on another day in its place and offer its expiation.

Hazrat Sulaiman bin Abi Dawood narrates that Hazrat Ata bin Abi Rabah was asked: If a person is continuously fasting for sixty days and Eid-ul-Fitr or Eid-ul-Adha comes in between, what should he do? He replied: He should not fast on that day, then continue his fasts afterwards.
