I wore socks while in a state of ritual purity, and I wore boots over them and wiped over the boots. Does the wiping become invalid if I take off the boots?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: If I wear socks while in a state of ritual purity, and then I wear military boots over them, and the midday prayer time comes and I wipe over the boots, and after the prayer I take them off, and at the afternoon prayer I want to wipe over the socks, is that permissible for me?

Answer:
No. If you started the wiping over the socks, there is no harm; it is valid, even if you take off the boots and the gaiters. The criterion is the beginning. If you started over the socks, there is no harm in removing what is over them. But if you started over the boots, then if you take them off, the wiping becomes invalid. Yes.
