Equal distribution of the qurbaani animal

Q: Alhamdulillah my parents had slaughtered a cow for Eid which they included shares for myself, my daughter and my wife. I had told them that I would pay for my share as I wanted to pay for my waajib qurbani.

1. Although I asked my mother earlier, she had only given me the price of the qurbani on the day it was slaughtered. As I did not have the bank details I could not make the payment before it was slaughtered. Can I still pay my parents for my qurbani?

2. It is my understanding that my father paid for the qurbani while my mother handles the distribution and my father does not mind. My mother has told us on a few occasions that we should let her know whatever we want from the cow. Should there be any extra caution exercised to ensure that no interest(ribaa) is given or taken?

Paralyzed person delaying in changing after passing stool

Q: Most of my body is paralyzed. I have a caregiver to assist me for my basic needs. Most mornings when the caregiver arrives around 8:30 or later upon checking, we realised that I have passed stool. Some mornings I do not pass. After eating or being awake for some time I sometimes make more stool.

1. If I do not get a smell is it fine for me to continue with eating and other work or should I rather check?

2. Can I do exercises and drink hot water before checking and changing to try to ensure that I just need to change once for the morning?

3. Some mornings I am not well or very tired and find it difficult to sleep after waking up to change. Can I continue sleeping after the caregiver comes or should I break my sleep and check to see if I need to change?
