Is it permissible to take a bird out of its cage in a place where there is a Mus'haf, given the fear of its droppings falling on the Mus'haf?

According to the stronger opinion, bird droppings are pure. It is permissible to release a bird in a place where there is a Quran, and there is no obligation to move the Quran away, as the bird's flight does not constitute disrespect towards it. The falling of droppings on it is a doubtful matter. It is advised to disregard obsessive thoughts and not pay attention to them.
