He should either start to recite again or if he had finished Al fatiha, he should go for Ruk’u

If a person starts to recite during prayer then his mind wanders off and he is not concentrating, then when he finally realizes that he is day dreaming, he cannot remember well what he recited earlier, what should a person do in this case?

There is a hadeeth of RasoolAllah s.w.a that he said the best time to pray isha is nisful layl? So I do not end up going to congregation for Isha. I stay at home expecting to pray at the best time.

If somebody was traveling back and front on not trips, but for other important reasons and that person missed some prayers and doesn’t know exactly how much of prayers he missed what does such a person do?
