Various Masaail on Qadha Salaah

Making qadha if haidh started during a salaah time

Q:

1. My menstruation cycle is regular in the sense that I have 14 clean days, 1 day istihaza and 10 days haiz. It's the same every time. So it starts at 4.43pm. I am usually always alert about performing my asr salaah before the time of haiz starts. Unfortunately today I was unwell earlier and had to sleep and over slept and only awoke after the time of haiz began. Will this asr Salaah be considered as qaza?

2. As a saahib tartib if I make ghusl and I have only enough time to perform the fard salaah and not the qazaa. When do I read the qazaa?

Performing qadha of missed salaah

Q: I want to ask a couple of questions regarding qadha prayers.

1. What should be my niyaah when praying qadha namaz and what time of the day should I offer it?

2. How should I offer my qadha prayers, given that I have the following ones left? (I have only made an estimation, because I don't remember the count exactly): Fajr-4, Zuhr-6, Maghrib-1, Isha-Salaat-ul-witr of 2-2.5 years (around 800)

3. Do I need to offer all of the witr prayers or is there any alternative to it? I request you to outline the complete method, so that I can offer them as quickly as possible.
