Yahya related to mefrom Malikthat Abdullah ibn Dinar said, "I saw
Abdullah ibn Umar urinating while standing."
Yahya said that
Malik was asked if any hadith had come down about washing the private
parts of urine and faeces and he said, "I have heard that some of
those who have passed away used to wash themselves of faeces. I like
to wash my private parts of urine."
