Wudhu

Q: ​Does normal white vaginal discharge break wudhu in Hanafi Fiqh?

Q: I have scratched the inside of my eye, which is leading it to constantly tear up. Are these tears impure because my eye is sore when I close it and it gets teary and the tears have went on my bed.

Q: Does mosquito sucking one's blood break wudu? 

What if the mosquito took so much blood that if killed, the blood would flow?

Q: Will my wudhu be valid if I use earseeds? It involves placing adhesive pellets on the ear pressure points for 3 to 4 days at a time.

Q: What is the ruling of drinking the leftover water of wudhu (fadl wudhu) whilst standing? 

In Dars Tirmizi (vol. 1, pg. 259) — taken from Duroos Madaniyya of Moulana Husain Ahmad Madani رحمة الله عليه — it is mentioned that Ibn Abidin (al-Shami) did not regard it as mustahabb, and that the ahadith on this issue cannot be used to establish istiḥbab. 

However, in Fatawa Mahmoodiyyah (vol. 8, pg. 123) the words of Ibn Abidin (al-Shami) in Radd al-Muhtar are quoted as proof that drinking fadl wudhu whilst standing or sitting is mustahabb. 

My questions are: 

1. According to the Hanafi madhhab, is drinking fadl wudhu mustahabb or not? 

2. What is the correct position of Ibn Abidin (al-Shami) in this matter? 

3. If it is mustahabb, is it specifically recommended to drink it while standing, or is sitting still better? 

4. How should the apparent contradiction between Duroos Madaniyya/Dars Tirmizi and Fatawa Mahmoodiyyah be reconciled?

Q: I put a plaster on the back of my mother's foot at around isha as she had a blister. She still had it on until the next day Maghrib because she forgot about it. Are her prayers invalid?

Q: From my understanding, the hair transplant treatment is permissible. After having it done, one is required not to let water touch the scalp for about 3 days. How then should one do masah?

Q: Is it necessary to rub the eyes when making wudhu?  If a little dirt is stuck in the corner of the eye, is wudhu accepted?

Q: Will my wudhu or ghusal be accepted if I have instant henna/mendhi on my hands. If not, why?
