AhsanAllah Ilaykum, I was in the state of major impurity and cut my finger and had to put a bandage on my finger, do I have to take it off to make ghusl? جزاكم الله خيرا

If your doctor tells you that it doesn't cause a problem for your health, then yes u can take it off do ghusl and replace it. If he says no then you can wiped over it, and if u can't wipe over it then no problem make your ghusl without that part.
