slaam so i have missed many years of salah. so i would like to ask the following 1.) from what age would you have to make up for missed prayers? 2.) when doing the intention would i have to make intention for the specific day. or can i just say "i intend to say 4 fard rakats of salatul qada..." in other words would would i say for the intention. as doing qada for a specific day seems somewhat complicated 3.) im guessing qada cannot be prayer in the disallowed times such as after asr. would this be correct? thank you jazakallah
