Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

 

It seems that you are suffering from incontinence (inability to control your bladder/bowel) then you certainly fall in the category of those who are allowed special dispensations because of your specific condition.

 

In this case, all that you need to do is to wash and perform your wudhu as closely as possible to the salah you are about to perform. Once you have done so, you need not to worry about what happens after. Your salah is perfectly valid because of your specific health condition.

 

For Allah says, “Allah does not wish to impose on any soul such burdens that it has no strength to bear.” (Al-Baqarah 2: 285)

 

Therefore, you need not worry about the validity of your Hajj as long as you have taken all due precautions that you can because of your medical challenges. You may wear a pad or underwear in this case, although a person who is not a similar situation cannot do so.

 

You should know that Islam is a manifestation of divine mercy; as such, it is easy to practice for men and women facing diverse challenges.

 

Almighty Allah knows best.
