Purity of tayammum Body Part
You have stated that things on which we can do tayammum should be pure. Is it obligatory for body parts involved in tayammum — i.e. forehead and back of the hands — to be pure as well?
Gender change
Some people have the appearance of men. They have female psychological and sexual tendencies though. If they do not undergo the operation of sex change, they might commit sins insofar as their sexual behavior is concerned. Is it permissible for them to undergo such an operation?
Khums on books
Are the books bought by a student subject to khums if he does not have any source of income and buys them with his father’s money or with a loan given to him by the university? And what if his father has not paid khums on the money used to purchase the books?
