Isa bin Abdullah (may Allah have mercy on him) narrates from his father, Sayyiduna Abdullah bin Unays (may Allah be pleased with him): "On the day of Uhud a water-skin was brought to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) urinated beside the water-skin, then drank water from it."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these hadiths from Ubaydullah bin Umar (may Allah have mercy on him) except Abd al-A'la (may Allah have mercy on him), and Muhammad bin Uthman al-Uqayli (may Allah have mercy on him) and Abu Isa Abdullah bin Unays (may Allah be pleased with him) are alone in narrating them."
