Hadith 8:2622
Abu Bakr narrated to us, he said: Salam narrated to us, from Ibrahim, from Abu al-Sha'tha', who said: We were sitting with Abdullah ibn Umar in Mina, and food was brought to us. A son of his moved aside and said, "I am fasting." He said, "Eat, for these are days of eating and drinking." He said: So he broke his fast.
حدثنا أبو بكر قال نا سلام عن إبراهيم عن أبي الشعثاء قال كنا جلوسا مع عبد الله بن عمر بمنى فأتينا بطعام فتنحى بن له فقال إني صائم فقال اطعم فإنها أيام أكل وشرب قال فأفطر
