The duration of wiping over the leather socks and when it begins

Question:
This is a question we always ask, Honorable Shaykh, on the Fatwa program. The questioner says: I performed wudu (ablution) with water in the prescribed manner, then I put on my leather socks and traveled to a distant park where there was not enough water with us for wudu. So I performed tayammum (dry ablution) for prayer and remained in this state for three days. Then water became available for us. The question for Shaykh Salih al-Fawzan (may Allah preserve him) is: Has the duration for wiping over the leather socks expired? If it has not expired, is it permissible for me to wipe over the leather socks with the purity of tayammum? Knowing that I put them on three days ago with the purity of water?

Answer:
The duration of wiping begins from the state of ritual impurity after putting them on. Yes. So if one performs wudu from a state of ritual impurity after putting on the leather socks, the duration of wiping begins from that time: for the resident, one day and one night; and for the traveler, three days and their nights. So you consider the first wipe after the state of ritual impurity—the first wipe of the leather socks after the state of ritual impurity—as the point from which the duration of wiping begins. Yes?
