Ramadhaan & Fasting

Giving money to a student to assist him in his studies for the missed fast and salaah of one's father

Q: Dad was ill in hospital and shortly after he got admitted he passed away. He did not give wasiyat for his missed fast and salaah, so I've taken it upon myself to fulfil some sort of kaffarah (fidyah) on his behalf, and insha'allah Allah will accept.

In terms of spending the kaffarah (fidyah), there is a young baligh male who is from a poor family and needs to sort out his final year of studies in order for him to get his degree/diploma in order to move forward with his life.

Is it possible for me to give him the money or a 3rd party who is currently financially responsible for his payments to pay off his final year of studies?

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?
