Invalid masah on short socks

Walekumussalam,

If the socks do not cover the ankles at all or even slightly (meaning the ankle remains exposed from below), then wiping over such socks is not valid. Therefore, the prayer performed after wiping over such socks will also not be valid, and it will be necessary to repeat those prayers.

This is because one of the conditions for wiping over socks is that: According to the Hanafi school as well as the majority of scholars, the socks must cover the feet up to the ankles. In fact, they should be high enough that even while sitting, the ankles do not become exposed. Therefore, if the socks are so short that the ankles remain exposed, wiping over them is not permissible; rather, in such a case, washing the feet is obligatory.

Hence, if you have been wiping over such socks for a year which did not cover the ankles, then the wudu performed with that wiping was not valid, and the prayers offered with that wudu must be made up (qada).

However, you may be reassured that since you did this out of lack of knowledge, there is no sin upon you, inshaAllah.

Gradually begin making up your missed prayers

Along with each obligatory prayer, add one or two qada prayers so that it becomes easy to complete them

And for the future, either use socks that fully cover the ankles, or wash your feet in wudu

May Allah grant you ease, accept your worships, and make this matter easy for you.
