Tawaaf

Performing tawaaf on the upper level

Q: If someone, as part of umrah, performs tawaf in the top level mataf (which is made for people with wheelchairs), will the tawaf be valid even if he is healthy and able to perform tawaf on the ground floor? I am asking since a family member is wheelchair bound, and it is easiest if the whole family sticks together and perform umrah together with him rather than splitting up, which would mean that everyone would perform tawaf on the top floor.

Area below the navel becoming exposed while making tawaaf in ihraam

Q: When wearing the ihraam cloth and making tawaf around the ka'bah, I am afraid that part of my awrah (just below the navel) will be visible at times, especially when flipping the cloth to the idhtibaa' position etc, since I am not used to wearing this cloth. If my awrah shows, will the tawaf still be valid. Will I have to pay any compensation for it?

Making tawaaf on a wheelchair

Q: I am planning to go for umrah with my father who is elderly. He can walk slowly, but it would take extremely long time for him to perform the tawaafs and sa'ee walking, and he would have to stop many times to rest. Will it be permissible to take him in a wheelchair, even though he technically can walk, since this would be easier for him?
