Narrated//Abdullah ibn Umar: Marwan al-Asfar said: I saw Ibn Umar make his camel kneel down facing the qiblah, then he sat down urinating in its direction. So I said: AbuAbdurRahman, has this not been forbidden? He replied: Why not, that was forbidden only in open country; but when there is something between you and the qiblah that conceals you , then there is no harm. Sunan Abu-Dawud, Book 1
