English Translation
Narrated Um Al-Fadl bint Al-Harith: "While the people were with me on the day of 'Arafat they differed as to whether the Prophet was fasting or not; some said that he was fasting while others said that he was not fasting. So, I sent to him a bowl full of milk while he was riding over his camel and he drank it."
