the grave is due only to a person’s own urine, which frequently gets on him, not to animal urine, which only rarely does so. It is established in the two Sahīhs that the Prophet, may Allah bless him and grant him peace,
“instructed the men of ʿUraynah, who had only recently embraced Islam, to join the camels collected as charity, and ordered them to drink their urine and milk.”
Yet he did not instruct them to wash whatever touched their mouths and hands, or to wash the vessels containing the urine, despite their having only recently embraced Islam. Had livestock urine been like human urine, explaining this would have been obligatory, and it would not have been permissible to delay that explanation beyond the time it was needed. This is especially so because he mentioned the urine together with the milk, which is lawful and pure. Moreover, the Prophet’s prohibition of treatment with foul substances, may Allah bless him and grant him peace, is established through numerous reports.
Furthermore, it is established in the Sahīh that
“the Prophet, may Allah bless him and grant him peace, used to pray in sheep pens,”

Had their droppings been impure, their pens would have been like human latrines: he would either have forbidden prayer there altogether or prayed there only with a protective barrier. Since the Sunnah permits this, anyone who equates human urine with sheep urine is contradicting the Sunnah.
