The Prophet ﷺ broke his fast at Arafah. Umm Fadl sent him some milk, and he drank it.
حدثنا عفان حدثنا وهيب حدثنا أيوب عن عكرمة
أن النبي ﷺ أفطر بعرفة قال بعثت إليه أم الفضل بلبن فشربه
Its isnad is sahih. Tirmidhi narrated it through the route of Ayub, from Ikrima, 2:56, and we have referred to it at 1870. See also the previous hadith.
