Is the wudu' of a person valid if he interrupted his wudu' to put on a sock after washing each foot?

Question:
A questioner says: A man performed wudu', and after washing his right foot, he stood up and put on a sock. Then, after washing his other foot, the left one, he stood up and put on the other sock. Is his action valid?

Answer:
There is no harm in that, but he does not wipe over them. Putting on socks is fine; he wears them in any state. However, if he intends to wipe over them, he must first wash his feet, then put them on, and he must put them on after achieving complete purity. The saying of the Messenger of Allah (peace and blessings be upon him), "Leave them, for I put them on while pure," indicates that complete purity is required. This is because the Messenger (peace and blessings be upon him) was performing wudu', and al-Mughirah ibn Shu'bah (may Allah be pleased with him) was present. When he reached the feet, al-Mughirah ibn Shu'bah (may Allah be pleased with him) reached out to remove them from the feet of the Messenger (peace and blessings be upon him). He said to him, "Leave them, for I put them on while pure," and he (peace and blessings be upon him) wiped over them.
So his saying, "I put them on while pure," is evidence that complete wudu' is required before putting on the leather socks or socks. This is the correct position held by the majority of scholars.
