Salaah

Fidyah for a person with dementia

Q: My grandmother passed away some years ago. During the final portion of her life (approximately two years), she suffered from dementia, due to which she would be very confused as to what day it was, whether she had eaten or not, etc. At this time, she stopped performing salaah as well. My questions are: 

(1) Does fidyah need to be paid for the all salaah she did not perform during the period she suffered from dementia? 
(2) If yes, can the fidyah be paid from her estate/wealth? 
(3) If the fidyah cannot be paid from the estate, who is responsible for paying it?

Maintaining consistency in performing one's salaah

Q: I would like to seek advice on how one can become consistent in waking up for Fajr salaah and maintaining consistency with all my daily salaahs. I find myself struggling, especially with Fajr, and at times I miss or delay other prayers as well. Could you please guide me on practical steps, habits, and any duas or actions that can help me stay firm and disciplined in my salaah? 

Going for umrah when one has outstanding qadha salaah

Q: Alhamdulillah by the mercy of Allah, I have been consistent with my salaah with Jamaat for many years, and have no qadha from the age of 17 onwards. However, before that unfortunately I used to miss most of my Salaah. 

My family wants me to go for Umrah but I don't feel it to be the right thing for me to join them, as I haven't completed my qadha salaah yet. I feel it's doesn't make sense to do that great but nafl amal when a compulsory amal is outstanding. I would feel extremely uncomfortable visiting the Kabah Shareef and Madinah, including the mubarak qabr of Nabi (sallallahu alaihi wasallam), and then conveying the durood with such major sins and unpaid debt on my shoulders. I understand that there is obviously barakah in Umrah, but there might be barakah in making qadha salaah as well (in my opinion). 

In addition, I find that my concentration and devotion to any nafl amal is weak and I always feel that I'm wasting time since I'm not prioritizing what is more important in the sight of Allah. Please advise.

Altering one's sitting posture after sajdah to avoid urine drops coming out

Q: I have a problem that when I go to sajdah, some drops of urine come out. So when I do sajdah, I do my best to prevent from this happening. For this I often do sajdah with my feets not touching each other in sajdah. 

Also when I rise from one sajdah I do not sit properly and then again go to the next sajdah. 

These acts prevent the drop of urine from coming out. 

Is this permissible for me or not to do during Namaz?
