Assalaamu alaykum. Please, is it true that it is from the Sunnah that whenever somebody goes to the toilet or restroom, they should wash their legs because they may have touched or stepped on impurity? If yes, then what is the quantity of water required? This has added to my Waswaas (obsessive whisperings), each time I go to relieve myself, I keep on pouring too much water (six or more kettles), which could be used for bathing, on my legs. Secondly, if there is impurity on my legs or hands and I want to perform ablution, must I wash the impurity first before performing ablution, or is washing them during ablution sufficient? May Allaah reward you. Wassalaamu alaykum.

All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

It is not from the Sunnah to wash the legs before or after entering the toilet or restroom. The basic principle is that any place which the feet walk over is ritually pure unless it is known with certainty to be impure. You must repel Waswaas and totally ignore it.

Also, you are not required to wash off the impurity before performing ablution or Ghusl (ritual bath); it is sufficient to remove the impurity during the ablution or Ghusl.

Again, you must disregard such satanic whisperings and pay absolutely no attention to them. Getting carried away with them leads to grave evils, as they are the work of Satan. For more benefit, please refer to fatwa 209290.

Allaah knows best.
