While urinating and defecating one should not face Qiblah

 Abu Ayyub narrated that the Prophet salla alayhi wa sallam said: ´´When you relieve yourselves, neither face not turn your back towards the Qiblah, but fave the east or the west.´´

Abu Ayyub said: When we came to Syria, we found there the lavatories already built towards the Qiblah. So we diverged from it and we sought forgiveness of allah.
