Ruling 847 — Prayer (Ṣalāh)

If the small items of clothing of someone performing prayers that cannot cover the private parts – such as socks or a cap – become impure, in the event that they are not made from an impure carcass or an animal that is an intrinsic impurity – such as a dog – prayers performed with them are valid. However, if they are made from an impure carcass or an impure animal, then based on obligatory precaution, prayers performed with them are invalid. However, there is no problem in performing prayers with an impure ring.
