Ash-Shaykh Bin Baaz, rahimahullah, was asked the following question,
س: بعض الناس يقول الحيوانات ما لها عقل؟
Question: Some people say that animals don’t have a intellect?
الشيخ: عقل يليق بها، لها عقول تليق بها، العقل البهيمي يليق به، يعقل يشرب يأكل ويسافد وهكذا.
“They have a intellect according to what suits them as animals, an intellect which they drink by, eat by, mate by and so on.” End translation. [Reference]
In other words, they don’t have a intellect like the intellect of human beings. For that reason, they aren’t held responsible like humans are held responsible for their actions.
