What is the method for making up prayers missed over years, and is it a condition to specify the day in the intention, and must prayers performed in ignorance of their rulings be made up, and if so, should they be made up before the missed prayers, and is chronological order a condition in making up missed prayers?

Whoever has missed prayers must make them up immediately, at any time, and specify the prayer being made up, not the day. The intended order among missed prayers is to make them up one after another. The majority of scholars believe that ordering is not necessary for numerous missed prayers. As for prayers performed in ignorance of the rulings of purification and prayer, one is not required to repeat them, because doubt after finishing an act of worship has no effect.
