What is the ruling on wiping over military boots (bistar) after putting them on while in a state of complete purity, then praying with them? Does this invalidate the ablution, and is the prayer valid?

It is permissible to wipe over military boots (Bustar) because they are considered similar to Khuffs (leather socks). For prayer to be valid with them, they must be pure, cover the ankles, be firmly on the feet, and be worn after a complete state of purity. The method of wiping is by placing wet fingers on the tips of the toes and running them up to the shins. The duration of wiping is one day and one night for a resident, and three days and nights for a traveler. The period begins from the first wiping after an event that necessitates ablution. If the Bustar are removed but socks remain, it is permissible to wipe over the socks, and removing the Bustar does not affect the ruling, as the ruling in this case applies to the socks.
