Mukhtasar Bukhari

Narrated Ibn Abbas (may Allah be pleased with them) that: I gave Zamzam water to the Messenger of Allah (peace and blessings of Allah be upon him) to drink, so he drank it while standing. In another narration, Ibn Abbas (may Allah be pleased with them) says that the Messenger of Allah (peace and blessings of Allah be upon him) was riding a camel that day.
