Setting
1- The Messenger of Allah (may Allah's peace and blessings be upon him) forbade fasting the two days: Eid al-Fitr and Eid al-Ad'ha; wearing a garment that is void of openings for hands; sitting on one’s buttocks while holding his both legs pulled back with his arms in case he wore only one garment; and praying after the Fajr and ‘Asr prayers
2- Did the Messenger (may Allah's peace and blessings be upon him) prohibit the fasting of Friday? He said: Yes
3- There is no fasting superior to the fast of my brother Dawūd; fasting half of one's life by fasting one day and eating one day
4- I witnessed Eid with ‘Umar ibn al-Khattāb (may Allah be pleased with him), and he said: These are two days that the Messenger of Allah (may Allah's peace and blessings be upon him) forbade fasting: the day of breaking your fast, and the other day in which you eat from your sacrifice
