Q: Please can you help me with the following:

When I flush the toilet, drops of water fall on the seat, does this make the seat napak? If something napaak falls on the toilet seat, I usually wipe the seat with a wet cloth then wipe it with a dry tissue. Sometimes my thigh gets a bit wet when I sit on the seat as the seat is not completely dry after I have dried it, will this make my thigh napaak?

Q: Chinese Sumi ink is used in certain types of Arabic calligraphy. I have recently found out that this ink is made using gelatine/animal glue from cows or rabbits. As there is no way to determine whether the gelatine is from halal slaughtered animals, is it permissible to use this ink for writing? In particular writing the Names and Praises of Allah Ta'ala and Aayat of the Quraan Majeed?

Q: Red wine grape extract is extracted with the remains of grapes (seeds, skin, etc.) after the fermentation process is completed of the wine. The remains of grapes are also dipped in fermentation solution... but the alcohol percentage in the extract is very small and according to some no alcohol. The alcohol is removed. is it impure or pure in skin toners or cosmetics?

This process of red wine extract is typically made from the skins and seeds of red grapes. The process involves crushing the grapes and fermenting the mixture to produce wine. After fermentation, the solid parts, including the skins and seeds, are separated from the liquid. The remaining solids are then dried and processed to create a concentrated red wine extract, which can be used for various purposes, including dietary supplements and skincare products. Is it pure or impure?
