It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that I did not prohibit fasting on Friday, but by the Lord of the Ka'bah, Muhammad (peace be upon him) prohibited it. By the Lord of the Ka'bah, I did not say that whoever enters the morning in a state of major impurity should not fast, but by the Lord of the Ka'bah! This statement was made by Muhammad (peace be upon him).
