Fasting being given priority over nafl ibaadat

Q: I would like to fast and try and see how far I can make it. The problem is that when I tried fasting last year, the medications I take for epilepsy are much stronger without food so I end up waking up after 11 or 12 noon most of the time and then don't have much energy for tilawat, zikr, etc.

Should I give fidya and put my tilawat, zikr, duaa, etc. first or fast? For me it's a matter of nafl or fardh, which is more important, the fast or the ibaadah and tilawat?

Stunning animals before slaughter

Q: Can Mufti Saheb please explain how come stunning of animals before slaughter is not permissible. I only eat the meat of unstunned animals and my family members are saying that they have never heard of this and I'm making up my own rules and all these years everyone has been eating meat certified by Sanha.

I was also told that by stunning of all animals, is torture to the animal, can result in death, which is hard to ascertain at the time of slaughter, as the animal is already unconscious due to stunning, and that it also prevents the animal from kicking and the heart pumping out all the najis blood that makes it halaal, as the Islamic way of slaughter (as one has to cut the jugular and 2/3 arteries in order for all the najis blood to flow out) and that stunning of livestock (cows, sheep etc.) is reversible. In this case won't the meat of the animal that is stunned be carrion and haraam in any case?
