Al Salam Alaykum. I am currently facing some urinary incontinene in the form drops leaking out every few seconds throughout the day. After reading many online fatwas, I have went and bought some adult diapers to keep my underwear clean. My issue is that they aren't cheap, and I read that I need to change the diaper every prayer. What should I do in this case? Should I combine my prayers and only change 3 times a day or should I wear one for the whole day?
