Question: Is it permissible to keep a bird as a pet?

Answer: It is permissible to keep a bird as a pet provided that one takes proper care of it by feeding it timeously, giving it water and not harming it in any way.

A hadith in Sahih Bukhari states that a young Sahabi by the name of Abu Umair had a small bird as the pet, with the knowledge of  the Messenger Sallalahu  Alaihi Wasallam.  Another hadith narrated by Imam Bukhari in Adabul Mufrad (Pg.139) mentions that the Sahabah  Radhiallahu Anhum  were in the habit of keeping birds in cages.
