It is narrated on the authority of Abu Hurairah radhiallahu anhu:

The Messenger of Allah peace be upon him said: 'Beware of two curses.' They said, 'Messenger of Allah, what are the two curses?' He said: 'To relieve himself (urinate) on people’s path-ways and under the shades.'

It was narrated that Abu Hurairah radiallahu anhu said:

''The Messenger of Allah peace be upon him said: 'I am to you like a father to his son, and I teach you. So when you go to relieve yourselves, do not face the Qiblah or turn your backs towards it.' He ordered us to use three pebbles, and he forbade us to use dung and bones, and he forbade cleaning oneself with the right hand."
