What is said about Zamzam (water)
حَدَّثَنَا مُحَمَّدٌ ـ هُوَ ابْنُ سَلاَمٍ ـ أَخْبَرَنَا الْفَزَارِيُّ، عَنْ عَاصِمٍ، عَنِ الشَّعْبِيِّ، أَنَّ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ حَدَّثَهُ قَالَ سَقَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم مِنْ زَمْزَمَ فَشَرِبَ وَهُوَ قَائِمٌ. قَالَ عَاصِمٌ فَحَلَفَ عِكْرِمَةُ مَا كَانَ يَوْمَئِذٍ إِلاَّ عَلَى بَعِيرٍ.
Narrated Ibn `Abbas: I gave Zamzam water to Allah's Messenger (ﷺ) and he drank it while standing. `Asim (a sub-narrator) said that `Ikrima took the oath that on that day the Prophet (ﷺ) had not been standing but riding a camel.
