Abu Hurairah reported the Messenger of Allah ﷺ as saying “The bell is a wooden wind musical instrument of Satan. ”
Shaykh Umar Farooq Saeedi
Benefits and Issues: ➊ It is not permissible to tie bells or bell-like objects around the necks of animals.
➋ The prohibition of other musical instruments is also established from the ahadith.
➌ Similarly, keeping a dog is impermissible if it is merely for display of awe or for adornment. If it is with the intention of protection, then it is permissible.
