Qadha Salaah

Q: If someone forgets to pray Zuhr Salaah and he now prays Asr Salaah before he remembers that he had not prayed Zuhr Salaah, what should he do?

Q: I have missed so many salaah during the last 10 years since becoming baaligh. I have no idea how many and cannot estimate. It is a major sin but I don't know how to go about rectifying it. Should I just make qadha for 10 years because it's impossible to calculate?

Also, do I include Witr in my qadha. 

Q: I have many qadhaas over the past 3 or 4 years. I've tried guessing but I have absolutely no idea, records, nothing. I usually pray all 5 prayers on time now, so would it be okay for me to start praying my qadhaas without making an estimate?

As I've mentioned, I don't have the slightest clue with which to make an educated guess. The longer I keep trying to estimate, the longer it gets put off. It's been two years already.

Q: If a woman gets her haidh during the salaah time, and she hadn’t yet performed the salaah of the time, will qadha of that salaah become compulsory upon her?

Q: When performing qadha salaat (qadha umri) at home, do I need to recite Iqamat?

The qadha salaah that I was offering was not missed by me in the first instance. I had offered them but later it transpired that those salaat were not valid. For such salaah, should I recite iqamat when performing it at home?

Q:

1. My parents passed away when I was a minor. My mother was shot when I was 2 years old and my father was shot when I was 6 years old. Does that make both of them shaheed?

2. I'm unaware of any qadha salaahs or fast if they had any. I was told that my father used to cover up qadha salaahs, I'm not sure if he completed it. What must I do on behalf of them? I would have estimated how many salaahs and fasts they had from the age of their puberty till demise and paid for every salaah and fast but I'm not a wealthy person. I dont know if I should give kafaarah on their behalf for any qadha salaah and fasts and how much I need to pay for them both as I am unaware of the amount of qadha salaahs or fasts for them both. What must I do?

Q: How should salaats missed over several years be performed and discharged in a situation where one has no record of the number of salaats missed and from when?

One also does not know when one had become baaliq, in which case, does missed salaats have to be estimated from the age of 12 or 15?

Q: Dad was ill in hospital and shortly after he got admitted he passed away. He did not give wasiyat for his missed fast and salaah, so I've taken it upon myself to fulfil some sort of kaffarah (fidyah) on his behalf, and insha'allah Allah will accept.

In terms of spending the kaffarah (fidyah), there is a young baligh male who is from a poor family and needs to sort out his final year of studies in order for him to get his degree/diploma in order to move forward with his life.

Is it possible for me to give him the money or a 3rd party who is currently financially responsible for his payments to pay off his final year of studies?

Q:

1. How do we know number of missed prayer when we used to pray occasionally (based on years) and how to perform those missed prayers?

2. Can we attach one extra prayer in lieu of missed prayers in Fajr and Maghrib?
