Ibn Majah

Benefit:
The meaning of being created from devils is that a habit of mischief is found in them.
The rancor of the camel is well-known; therefore, there remains a danger that, given the opportunity, it may try to cause harm.
Otherwise, urine and droppings are found in the enclosures of both goats and camels.

736. Commentary: The reason for the prohibition of prayer in camel enclosures is not impurity; otherwise, prayer should also be prohibited in goat enclosures, whereas explicit permission for praying in them has been mentioned. The practical narration has also already been discussed. (See Hadith: 703) The reason for the prohibition could be that the camel has been called "Shaytan al-Dawab" (the devil among animals), meaning it is a very mischievous animal—powerful and stubborn. The person praying will constantly be apprehensive that the camel might snatch something with its mouth, sit on him, or kick him, so his attention will remain on the camels instead of the prayer. In this way, humility and submissiveness (khushu‘ and khudu‘) will not remain. If the enclosure is empty of camels, can prayer be performed there? Apparently, it can be performed, because the aforementioned danger no longer exists. However, it is possible that due to the association with Shaytan, the effects of Shaytan remain in the empty enclosure as well; therefore, based on the apparent wording, it is better to avoid it.
