Muslim must beware of najaasah (impurity) and try to avoid it as much as he can. It was narrated that Ibn ‘Abbaas said: The Messenger of Allaah (peace and blessings of Allaah be upon him) passed by two graves and said,
“They are being punished, but they are not being punished for something that was difficult to avoid. One of them used to walk about spreading nameemah (malicious gossip) and the other used not to take care to avoid getting urine on himself.”
Narrated by Muslim, al-Tahaarah, 439
What is meant is that he did not take precautions to avoid getting it on himself. Hence it is permissible to urinate standing up so long as a person can be sure that he will not get splashes of urine on his clothes or his body.
