Ikrimah (may Allah have mercy on him) says that once I went to the house of Hazrat Abu Hurairah (may Allah be pleased with him) to serve him. I asked him about the issue of fasting on the Day of Arafah in the plain of Arafat. He replied that the Noble Prophet (peace and blessings be upon him) forbade fasting on the Day of Arafah in the plain of Arafat.
