عَنْ يَزِيدَ بْنِ عَطَارِدٍ رَضِيَ اللَّهُ عَنْهُ قَالَ وَكِيعٌ السَّدُوسِيُّ أَبُو الْبَزَرِيِّ قَالَ سَأَلْتُ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ الشُّرْبِ قَائِمًا فَقَالَ قَدْ كُنَّا عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَشْرَبُ قِيَامًا وَنَأْكُلُ وَنَحْنُ نَسْعَى
Abu Bazri Waki’ Sadoosi narrates, he says: I asked Sayyiduna Ibn Umar (may Allah be pleased with them both) about drinking water while standing. He said: In the time of the Prophet Muhammad (peace and blessings be upon him), we used to drink while standing and also eat while walking.
