Is it prescribed for one who has incontinence to sprinkle water on his underwear so that he is not afflicted with waswasah (whispers of doubt)?

Question:
He says: Honorable Shaykh, may Allah grant you success. Some jurists mention that one who has incontinence should sprinkle water on his underwear so that he is not afflicted with waswasah. Is this statement correct? Regarding the one who has incontinence

Answer:
and the woman with irregular bleeding, it is obligatory for her to place something on her private parts, binding something on her private parts to prevent the urine from leaking, so that it does not reach her clothes or anything else; this is sufficient, praise be to Allah. The Messenger (peace and blessings be upon him) ordered the woman to use a thick pad, meaning she places a cloth or bandage on her private parts to prevent leakage, with cotton in it. Nowadays, they have medical pads that have made this matter easier for women. However, if urine reaches the cloth due to incontinence or otherwise, it must be washed if he is certain of this. As for mere doubt, doubt does not obligate anything; the default is purity.
