The forbidden water closet 

In his Zād al-Ma3ād — Imām ibn al-Qayyim رحمه الله mentioned that confronting from the front/behind while relieving is forbidden if it is in the direction of the Qibla.

He goes further and mentioned that there are more than 10 odd indications (dalīlan) that there is a forbiddance, whether we speak of relieving in an open field or a place that is surrounded with what can be seen as boundaries. This is the most correct in the madhāhib (schools of Fiqh) according to him.
