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- These are two days which the Messenger of Allah (may Allah's peace and blessings be upon him) prohibited fasting on: the day you break your fast (Eid al-Fitr) and the day you eat from your sacrificial animals (Eid al-Ad'ha)
3- Did the Messenger (may Allah's peace and blessings be upon him) prohibit the fasting of Friday? He said: Yes
4- 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
