Does the ablution become invalid by removing the bandage that was wiped over?

The questioner : The questioner says: If one of us has a small piece on his hand, like a bandage for a wound, and he wiped over it and prayed, and during the prayer he removed the piece that was bandaging the wound, does his ablution become invalid, like a splint?

The Shaykh : I believe the question has been posed to everyone. A person has a wound on his limb, on his hand. He placed a bandage on it, and when he performed ablution, he wiped over it, and wiping over it suffices for washing it. Then he removed it during his prayer, or before his prayer, or it came off on its own. Does his ablution become invalid?
The answer is that his ablution does not become invalid, because when he wiped over it, his purity was completed in accordance with the texts of the Shari'ah. So if he removes it, that has no effect. An analogy to this, from some angles, is if a man wipes over his head and he has hair on it, then he shaves this hair; we say that your purity is not invalidated by the removal of what was wiped over. Also, according to the stronger opinion, if a person wipes over his leather socks and then takes them off after wiping over them, the stronger opinion is that his purity is not invalidated. However, he does not put them back on and wipe over them again unless he performs ablution and covers his feet. First.
