It was narrated by Abu Dawud (3). This is a specific [ruling] which takes precedence over the general [nature] of what they narrated. From Jabir ibn Samura, that a man asked the Messenger of Allah (may Allah bless him and grant him peace): "Shall we pray in sheep pens?" He said: "Yes." He asked: "Shall we pray in camel resting places?" He said: "No." Narrated by Muslim (4). From al-Bara', he said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Do not pray in camel resting places, for they are from the devils." Narrated by Abu Dawud (5). From Usayd ibn Hudayr, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Pray in sheep pens, and do not pray in camel resting places." Narrated by Imam Ahmad in his "Musnad" (6). A prohibition implies prohibition [tahrim], and this is a specific [ruling] that takes precedence over the general [nature] of what they narrated. This hadith was also narrated from Ibn 'Umar, Abu Hurayra, and 'Abd Allah ibn Mughaffal; al-Athram narrated them (7).

As for the latrine, the ruling is established regarding it by analogy [al-tanbih], because if one is prevented from praying in these places due to them being sites of impurity, then the latrine is prepared for and intended for impurity, so it is more appropriate that it be prohibited. Some of our companions said: If the one praying is aware of the prohibition in these places, his prayer is not valid, because he is disobedient by praying in them, and an act of disobedience cannot be an act of drawing near [qurba] nor an act of obedience. If he was not aware, is his prayer valid? There are two reports. The first is that it is not valid, because he prayed in a place where prayer is not valid with knowledge, so it is not valid with ignorance, like praying in an impure location.
