Hadith 15:381
Abu Bakr narrated to us, he said: Hafs narrated to us, from Ubayd Allah, from Nafi’, from Ibn Umar, he 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 حفص عن عبيد الله عن نافع عن بن عمر قال كنا نشرب ونحن قيام ونأكل ونحن نمشي على عهد رسول الله صلى الله عليه وسلم
