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 or some other man to announce during the days of Tashreeq that: "Only a believing servant will enter Paradise, and these are the days of eating and drinking."
It is narrated from Abu Murrah, the freed slave of Aqeel, that he and Abdullah bin Amr went to the service of their father, Sayyiduna Amr bin Al-Aas (may Allah be pleased with him), on the first or second day after Eid al-Adha (the 11th or 12th of Dhul-Hijjah). Sayyiduna Amr bin Al-Aas (may Allah be pleased with him) served food for both of them. Abdullah said: I am fasting. Sayyiduna Amr (may Allah be pleased with him) said: Break your fast, because the Messenger of Allah (peace and blessings be upon him) commanded us to break our fast during these days and forbade us from fasting. So Abdullah bin Amr broke his fast and ate the food, and I also ate with them.
