It is narrated from Sayyiduna Bishr bin Suhaim (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) ordered him to make an announcement during the days of Tashreeq. In the narration of Janab Mukhrami, it is mentioned that he sent him to make an announcement during the days of Mina that only believers will enter Paradise, and indeed the days of Mina are days of eating and drinking. I have explained this complete chapter in the Book of Fasting.
