Wisdom behind permissibility of wiping over leather socks:
Wiping over the leather socks aims at ease and facilitation for Muslims who find it hard to take off the socks or leather socks to wash their feet, especially in the severe cold weather and during travel.
The time limit for wiping:
A resident: one day and night (24 hours).
A traveler: three days and nights (72 hours).
The duration for wiping begins from the first time one wipes over the socks or leather socks after breaking his ablution.
How to wipe over the socks or leather socks:
1. Wet your hands.
2. Pass your hand over the top of your foot (from the toes to the lower end of the shank).
3. Use the right hand for the right foot and the left hand for the left foot.
Wiping gets invalidated by:
1. what entails a ritual bath.
2. the expiration of the permissible time duration.
