(49) باب صِيَامِ أَيَّامِ التَّشْرِيقِ
Abu Murrah, the client of Umm Hani, entered along with 'Abd Allah b. 'Amr upon his father 'Amr b. 'As and he brought food for him. He said:
Eat. He said: I am fasting. 'Amr said: Eat, these are the days on which the Messenger of Allah (ﷺ) used to command us to break fast, and forbid us to keep fast. The narrator Malik said: These are the day of al-tashriq (i.e. 11th, 12th, and 13th of Dhu al-Hijjah).
