Tahaarat

Q: Is it allowed to urinate standing using a urine pot which does not splash urine and keeps the clothes clean?

Q: A 87 year old male is permanently taking over 7 different medications, including insulin injections twice daily. After he had rectal operation to remove cancer, he cannot control his bowel and bladder very well. Before this he prayed 5 times daily. The situation is this:

He has to visit the toilet frequently for bladder and bowel. His clothes always have some napaaki on them. He is not fit and healthy enough to perform istinja/ wuzu without making more napaaki. He is only able to have full bath/change clothes every 1 or 2 weeks. He can do istinja/ wuzu and change clothes for Eid prayer, but not daily. Besides this, he is alright and looks fit and healthy for his age, he has no other mobility problems, and we thank only Allah for this.

Mufti Sahib, so if (1) istinja/ wuzu is a problem and (2) changing clothes frequently is also a problem, both problem are affecting this person. What is the ruling regarding salah, i.e. Taharat, tiyamum etc?

He has not read namaz for past 12 months due to these issues, but he desperately wants to read namaz.

Q: 

1. Can I read namaaz with the same wudu which I made before ghusl?
2. I have wudu and I changed clothes infront of my wife, do I still have wudu?

Q: I have a question regarding discharge. Sometimes the flow is constant, sometimes very less. Do I need to repeat my wudhu before every prayer? e.g: Will the wudhu for tahajjud suffice for fajr if there is no discharge and likewise for asr/maghrib?

Q: Can you provide guidelines how to perform istinja whilst fasting in a way that prevents water from entering and breaking the fast?

Q: If a girl thinks of the opposite gender, some normal day to day things, nothing romance and she is not sure that something has came out of her private parts. She suffers a lot of vaginal discharge everyday. So she performs her namaaz but afterwards she sees a white mark on her pants. Must she repeat her namaaz?

Q: I find wetness in my private parts all day long (75 percent of time in 24 hours). It's watery. When it dries I can't see anything. After istinja if I wipe it, I still find some drops there. Today when I got up for fajr, I found watery substance with no colour in it. There was no stickyness. I was not even feeling like urinating and if sometime Ii feel like urinating during day or night it does not mean that I will just do it. I am highly confused for my taharat (purity). What should I do for offering namaaz? Are my clothes and myself impure? I can't wear panty and liners all day long, it creates itchiness.

Q: Do all my clothes become napaak through ihtilaam? After ihtilaam if I don't make ghusal and just change my clothes, do these clothes become napaak as well?

Q: 

1. Does wudu break when we bleed from any part of the body or just from the parts of wudu?
2. What if the blood has flown and we don't know? Will the salah be accepted in this case?
3. What if we have doubt whether the blood has flown or not where we can't see like on the back, etc?

Q: What is the difference of mani and discharge in women ie how would a woman know that it is discharge or some other thing in which ghusl becomes fardh?
