Ruling on the prayer of one who wipes over his shoes and then removes them

Question:
The questioner says: (N. M. Al-Shahrani): When I perform wudu at school to perform the Zuhr prayer, I wipe over my shoes; this is because it is difficult to remove the shoes and put them back on, and because the mosque is far from the restroom. So when I arrive at the mosque, I remove the shoes and pray. What is the ruling on that?

Answer:
No, this is not permissible. This invalidates the wudu. It is necessary to wear a leather sock that covers the feet, or a sock that covers the feet, and wipe over it, and keep it on until one prays. The leather sock or sock must remain on him until he prays.
As for wiping over the outside of the shoe and then removing it at the mosque, this invalidates the prayer. It is necessary for it to remain on him until he prays in it, if it covers the feet. A shoe that covers the feet, like a leather sock or a sock made of wool or cotton that covers the foot, is worn in a state of purity, one wipes over it, then prays in it, and does not remove it before the prayer.
