The Ruling on Urinating while Standing
Question :
What is the ruling on a person urinating while standing, is it forbidden or permissible?
Answer:
It is not forbidden for a person to urinate standing, because it has been authentically reported by Al-Bukhari and Muslim, on the authority of Huthaifah, may Allah be pleased with him, that the Prophet came to the rubbish pit of a people and urinated while standing.Permission to urinate standing has also been narrated from 'Umar, 'Ali, Ibn 'Umar and Zaid bin Thabit, may Allah be pleased with them, due to the above-mentioned Hadith. But it is prescribed by the Sunnah for a person to urinate sitting, according to the words of 'A'ishah, may Allah be pleased with her, who said: "Whoever told you that the Prophet urinated standing, do not believe him. He did not urinate except sitting." (Narrated by Ahmad, An-Nasa'i, Ibn Majah and At-Tirmithi) At-Tirmithi said: "This is the best and the most correct saying in this matter - also because it is better to guard and protect him from being splashed with his own urine."Source:
