The importance of Salaah

Q: I am inquiring regarding the prayer of an old woman in her 80s, who forgets daily essentials. For example, she forgets when it is time to eat food or did she already eat or not etc. She forgets her family members, for example if any name of her daughter or grand child is mentioned to her then she would hesitate to say who that person is; family member or stranger. But if she is reminded then she would know the person but again in a minute she would forget completely.

If she hears the Azan being called out then she quickly starts getting ready for salah and performs according to the best of her ability. Then, if she hears another masjid calling azan ~15 minutes later for the same prayer, she prays this salah again because she thinks she hasn’t prayed this salah yet.

Is this woman obliged by shariah to perform her five daily prayers? 

Q: I have many health problems including back pain, incontinence, tiredness, mentally and physically weak, etc. I spend most of the time resting on the bed. Doing wudhu and praying 5 times is very difficult for me. I feel unwell most of the time, doing wudu, praying salah take very long time and I become tired and stressed out.

I don't know any Muslim doctor to ask this and no one else can help me do wudu. Because my illnesses like back pain, tiredness go worse by wudu and praying, can I do tayammum instead of wudu? And pray salah sitting? I tried doing tayammum and pray sitting but still I struggle.

Q: I offer namaz alhamdulilah but I live in a shared flat with my cousin and he sleeps all day and works night shift and doesn't offer namaz. He is 10 years older than me. I have told him a few times to offer namaz but he doesn't. Will I get azaab (punishment) as well?

Q: I offer salaah regularly Alhamdulilah but I had a few questions in this regard:

1. Although I don't do hijab but whenever its salaah time I feel restless to pray. I am married and prefer to go out only after magrib so that I don't miss salaah but my husband says it's ok if you miss a salaah for which you can offer qadha later as my urge to pray sometimes causes hurdles in schedule of shopping or doing grocery shopping. Please advise on this.

2. I work in a school and offer Zuhr Salaah during working hours. Is it okay if I do the fardh of wudhu only and offer 4 fardh of zuhr only. Kindly advise on this.

Q: Alhamdulillah we have been married for 3 years. My husband has been struggling with his Salaah. He's not been punctual and misses a lot of his salaahs. It really gets to me as Alhamdulillah I try my best to be punctual. Sometimes I feel like I can't take it anymore. Please advise as to what I should do in this situation.

Q: A woman assists by feeding the poor with zakaah donations of food, hampers and vouchers, clothing etc. The problem is that this person does not perform salah at all. She's not listening to me reminding her. How will this affect this person when leaving this world in this state?

Q: At what age does salaah become compulsory upon a child?

Q: I was a Christian but now I converted to Muslim. I am living with a girl I didn't marry. I know its a big sin to commit zinaa but I did not have money to marry my woman who is a Muslim. My question is, can I still pray my five times salat in this situation?

Q: What is the ruling of the one who repents from kufr and fails to pray salaah?

Q: Is qadha prayers accepted by Allah?

If I go out shopping or to a wedding, can I pray qadha when I get home and is it accepted?
