Question:Regarding the issue of wiping the legs, if my leg fingernails are long and I doubt that water reaches the tip of my toes, do I have to repeat ablution?

Answer:In the name of Allah, be advised son that the moisture of the wiping hand does not have to be conveyed to what is hidden between the nail and the flesh, but it is obligatory to start wiping over the nail. If the nail is long outside the border - the area of the finger- it should not be wiped. Allah knows best.

Question:What is the ruling of a person who performs ablution with impure water, unaware of its impurity?

Answer:In the name of Allah, ablution is invalid, and the prayers that he performed with that ablution are also invalid. He must wash the organs with a pure water and repeat the prayers that he performed with invalid ablution. Allah knows best.
