Hadith 15:378
Abu Bakr narrated to us, he said: Mu'adh ibn Mu'adh narrated to us, from 'Imran ibn Hudayr, from Yazid ibn 'Utarid Abu al-Buzari, he said: Ibn 'Umar said: We used to drink while we were standing, and we used to eat while we were walking, during the time of the Messenger of Allah, may Allah bless him and grant him peace.
حدثنا أبو بكر قال حدثنا معاذ بن معاذ عن عمران بن حدير عن يزيد بن عطارد أبي البزرى قال قال بن عمر كنا نشرب ونحن قيام ونأكل ونحن نسعى على عهد رسول الله صلى الله عليه وسلم
