Abu Wa'il reported:
Abu Musa inflicted extreme rigour upon himself in the matter of urination and urinated in a bottle and said: When the skin of anyone amongst the people of Israel was besmeared with urine, he cut that portion with a cutter. Hudhaifa said: I wish that'your friend should not inflict such an extreme rigour. I and the Messenger of Allah ( صلی اللہ علیہ وسلم ) were going together till we reached the dumping ground of filth behind an enclosure. He stood up as one among you would stand up. and he urinated, I tried to turn away from him, but he beckoned to me, so I went to him and I stood behind him, till he had relieved himself.
