Using Chinese Sumi ink

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?

Red wine extract

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?

Meaning of Kalaamun naas when making dua in Salaah

Q: I am following Hanafi Fiqh.

1. In the current situation of Palestine, I have started reading Qunut e Nazila in Fajr prayer. I restrict myself with the Arabic dua from Quran and Hadith. However, I said one day, allahummansuril mujahideena fi filasteen (in Arabic). Would that be considered as Kalamun nas?

2. Secondly, could you please let me know about the guideline which will be easy for me to understand the Kalamun Nas discussed by the fuqaha. I have heard that if we are making dua in Arabic outside Quran and Hadith, it should not be in the classification of Kalamun Nas. However, this thing did not become clear so that's why I am refering to you.

Cleaning water splashes on the floor after flushing the toilet

Q: I spend a lot of time in the washroom, trying to clean impurities. This is because I worry about impurities like urine touching water which comes on my body. I worry about splashes that come while flushing when they land on the floor. Since the splashes from flushing are impure and there is water on the floor and when impurity mixes with a body of water that is less than a certain length and width (I forgot), the whole water becomes impure so I clean the floor as well and the slippers too because they touch the floor. The splashes from flushing also land on the sink nearby so I wash the sink also. I also have to wash the seat where the same splashes also come. Can I simply use the washroom without washing anything and only see if my body is visibly pure or impure and not worry about coming into contact with water that had come into contact with impurities?
