Sayyiduna Hudhayfah (may Allah be pleased with him) says: When it reached him that Sayyiduna Abu Musa (may Allah be pleased with him) (in order to avoid urine splashes) would urinate in a bottle and would say that when any individual from Banu Isra'il would get urine on himself, he would cut off that part, he (Hudhayfah) said: "I wish your companion would not be so strict." I saw myself walking with the Messenger of Allah (peace and blessings be upon him), and when we reached a place full of rubbish, the Messenger of Allah (peace and blessings be upon him) stood and urinated just like you do. Seeing this, I started to move away, but he (peace and blessings be upon him) said: "Come closer." So I came closer to him, until I was standing at his heels.

(Second Chain) Sayyiduna Hudhayfah (may Allah be pleased with him) says: I was with the Noble Prophet (peace and blessings be upon him) on a path, then he moved aside to a heap of a people’s rubbish, so I distanced myself from him, but he brought me close to him, until I was standing by his heels. Then he stood and urinated, then called for water, performed ablution, and wiped over his leather socks.

It is narrated from Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) came to a heap of filth belonging to a people and stood and urinated. Hammad bin Abi Sulayman (may Allah have mercy on him) said: The Prophet (peace and blessings be upon him) spread his legs apart.

It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: If anyone tells you that the Messenger of Allah (peace and blessings be upon him) urinated while standing, do not believe him, because since the Qur'an began to be revealed to the Messenger of Allah (peace and blessings be upon him), from that time he never urinated while standing.
