Salaah of a sick person

Q: A woman who is a Shaafi and doesn't have the strength to get out of bed for wudhu and salaah, what should she do?

Q: A person wakes up in need of a Fardh Ghusl 15 minutes before sunrise. There is no hot water and the person has chronic health issues. Using cold water will cause his health to deteriorate. It takes approximately 15 minutes to heat up sufficient water for Ghusl. If he waits, the time will expire and Fajr Salaah will become Qadha. What should be done in such a situation?

Q: I can not sit in salaah. I have knee problem and the doctor isn’t doing anything to help. I also have loud cracks when sitting down and standing up. Can you help me and tell me how I can sit because I am unable to sit in the positions in salaah. I am only 13 years old also and I have done lots of exercises and medicine but they didn’t help.

Q: If someone is ill and has some disabilities, doing wudu and praying salah will increase the illness. He doesn't have anyone to help him. Can he do tayammum and pray sitting down?

Q: If a person suffers from urinary incontinence and even by praying while sitting, urine comes out but while standing from prostration, urine comes out with more certainty, should he pray while standing or minimize the risk and pray while sitting?

Q: Can I combine my prayers? I have a urine condition where if I go to the toilet, then after a few minutes, I feel that there is a drop of urine coming out.

Due to this condition, I try to not go to the toilet in the daytime so that I can perform my prayers, but it is a painful process to suppress your need to relieve yourself.

Can I combine my Zohr and Asr prayers and then perform the Esha prayer with Maghrib?

Q: I have abit of arthiritis in my lower back and waist and I'm struggling with standing and sitting when performing namaaz. What will be best and permissible in my case... sitting position on the musallah without getting up or sitting on a chair?

Will I receive the same reward?

Q: While sitting and performing salaah, I mistakenly tied my hands after coming up from the sajdah of the second rakaat instead of placing my hands on my lap for tashahhud. Does sajdah sahw become compulsory, like it would be compulsory if I were standing and performing salaah and stood up by mistake and then sat down?

Q: An old person cannot get up easily from sajdah. He takes support by leaning on the ground/holding a chair next to him.

Is the above better or should he rather sit on a chair for sajdah?

Q: Due to being unwell, a person performs Salaah sitting on a chair:

1. In such a case, how does he perform the ruku and sajda? Does he lower only his head OR his entire upper body?

2. For the sajdah, does he have to extend his hands further than his knees, creating a "place of sajdah"?
