Does the purity of wiping over socks end when the socks are removed?

Q: A man wiped over his socks during his ablution, then removed them after finding a smell on them. He prayed without washing the area where they had been. What is the ruling on his prayer in this state?

A: If he removed them while still in the state of purity in which he had put them on, his purity remains, and removing them does not harm him. However, if he removed the socks after becoming ritually impure, his ablution is invalid, and he must perform the ablution again. This is because the ruling regarding the purity of wiping over socks has ended with the removal of the socks, according to the most correct opinion of the scholars.
And success is from Allah.
