عَنِ الصَّلْتِ بْنِ غَالِبٍ الْهُجَيْمِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ مُسْلِمٍ سَأَلَ أَبَا هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ الشُّرْبِ قَائِمًا قَالَ يَا ابْنَ أَخِي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَقَلَ رَاحِلَتَهُ وَهِيَ مُنَاخَةٌ وَأَنَا آخِذٌ بِخِطَامِهَا أَوْ زِمَامِهَا وَاضِعًا رِجْلِي عَلَى يَدِهَا فَجَاءَ نَفَرٌ مِنْ قُرَيْشٍ فَقَامُوا حَوْلَهُ فَأُتِيَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِإِنَاءٍ مِنْ لَبَنٍ فَشَرِبَ وَهُوَ عَلَى رَاحِلَتِهِ ثُمَّ نَاوَلَ الَّذِي يَلِيهِ عَنْ يَمِينِهِ فَشَرِبَ قَائِمًا حَتَّى شَرِبَ الْقَوْمُ كُلُّهُمْ قِيَامًا
Muslim (the Tabi'i) asked Sayyiduna Abu Hurairah, may Allah be pleased with him, whether it is permissible to drink water while standing. He replied: O nephew! I saw the Noble Prophet, peace and blessings be upon him, tie the knee of his mount and make it sit down, and I was holding the reins of that mount, and I had placed my foot on the front leg of the mount. Some people from the Quraysh came and gathered around the Noble Prophet, peace and blessings be upon him. A vessel of milk was brought to the Noble Prophet, peace and blessings be upon him, and he drank it while he was still on the mount. Then he handed it to the one who was on his right side and closest to him. The Noble Prophet, peace and blessings be upon him, also drank while standing, and the entire group also drank while standing.
