Reported by At-Tahāwi and others from Abu Dhibyān that “he saw ‘Ali urinate while standing, then he called for some water and he performed wudū and he wiped over his sandals (mas’h)―then he entered the Masjid, took off his sandals and prayed.”

Shaikh Al-Albāni stated: “This is authentic in accordance with the conditions of Bukhāri and Muslim.”[3]

Narrated Hudhaifa:

Once the Prophet (ﷺ) went to the dumps of some people and passed urine while standing. He then asked for water and so I brought it to him and he performed ablution.
