QUESTION
Some people wear diabetes CGM monitors to constantly check their glucose levels. It’s a small minimal invasive needle sensor. Each sensor lasts 14 days and stops if removed and will have to be replaced. How should one wearing this perform ghusl?
ANSWER
﷽
Wearing a CGM monitor is permitted, but it must be removed during the obligatory bath (ghusl), as it prevents water from reaching the skin, which is a required condition for the proper completion of ghusl.
Unlike a bandage or cast used to cover a wound, which may be kept on in certain cases of necessity and need during bathing, a CGM monitor is used for convenience to check glucose levels. It is not considered essential for most people with diabetes, as glucose levels can be monitored by other methods. Since this device is a convenience (manfaʿah) rather than a necessity (darūrah), it must be removed during the obligatory bath.
(See generally key Hanafī texts, chapter of bathing & sections on wiping over bandages)
