Qadha Salaah

Q: A person who is "saahibut tarteeb" was sitting in the jumuah bayaan when he realised that he hadn't performed fajr. He then planned that he will read his qada when everyone is reading their sunnats after the bayaan, before the khutba. However he had a dire need to go to the toilet and only returned when the Imaam was on the mimbar and azaan was called. So he sat for the khutba, read jumuah and performed his fajr qada after the jumuah salaah.

1. Is what he did correct?
2. If not, what must he do to rectify his actions?

Q: Is qaza namaz acceptable if the prayer was skipped on purpose due to laziness?

Q: Can we make qadha of witr Salaah also?

Q: If one comes out of a coma, will he have to make qadha for those salaah that he missed while he was in a coma?

Q: If you started praying fajr at 5.00am but sunrise was 5.01am and you finished praying at 5.02am. Is that classed as qadha late prayer?

Q: If one misses asr Salaah, when should he make the qaza, after magrib or after esha prayer?

Q: Should Qaza Salaah be performed immediately after the Fardh Salaah, or once all the Sunnah, Nafl and Wajib Salaah have been completed as well? Such a person has more than six outstanding Salaah.

Q:

1. Is Azaan Sunnat Muakkada for Qadha Salaats?
2. If one leaves the Azaan constantly for Qadha Salawaat, will he be sinful?

Q: When I was young and ignorant, I used to have bad habits. Two of these included masturbation as well as neglect of salaah. Nevertheless, Alhamdulillah, with the Hidayat of Allah I have mended my ways. My question is, I want to make up for the missed Salaah. Should I start making up from when I was 15, or from when I was 12 when I ejaculated? I am not sure when my ejaculations were clear and when it started becoming milky in appearance.

Q: Do I need to perform Sunnat-e-muakkadah of each Salaah for Qadha-e-umri?
