You shouldn’t repeat your prayer as long as it was complete and not nullified. You should however offer voluntary prayers to erase any loss of concentration in it.

My father is about 62 years old. He’s still pretty strong but just needs a chair to perform Salaah. Does he too have to go to the mosque (which is 3 minutes away from our house)? He claims that walking up the stairs of the building of the house is hard
