Unreviewed translation. All hadiths in this collection are available in five languages. Titles and introductions may remain in Arabic.

Abu Said Abdullah ibn Said al-Ashajj told us: Abu Khalid al-Ahmar told us, from Amr ibn Qays al-Mulai, from Abu Ishaq, from Silah ibn Zufar, who said: We were with Ammar ibn Yasir when a roasted sheep was brought to him. He said: Eat. Some people held back, saying: I am fasting. Ammar said: ‘Whoever fasts on the day about which people are uncertain has disobeyed Abu al-Qasim, peace and blessings be upon him.’ Related reports are narrated from Abu Hurayrah and Anas. Abu Isa said: The hadith of Ammar is hasan sahih. Most scholars among the Companions and the Successors follow this. It is the view of Sufyan al-Thawri, Malik ibn Anas, Abdullah ibn al-Mubarak, al-Shafii, Ahmad, and Ishaq. They disliked fasting the day about which people are uncertain. Most of them held that if someone fasted it and it turned out to be part of Ramadan, that person should make up a day in its place.
