Q: I know that if a person will be performing qurbaani, then he should avoid removing his hair and nails during the first ten days of Zul-Hijjah, until his qurbaani animal has been slaughtered.

However, when performing hajj, I am told that you should remove your hair and nails before the 7th Zul-Hijjah. My questions are as follows:

1. If you are performing qurbaani and hajj, when should you remove your hair and nails?

2. Do you need to perform the qurbaani yourself, or can it be performed at home (back in South Africa) by someone else (parents, siblings or your children)?

Q: When doing tamattu or qiraan hajj, will the damm-e-shukr suffice for one's normal qurbaani, or will the qurbaani have to be done separately? If one is unable to slaughter an animal for damm-e-shukr, then what should he do?

Q: Our Muslim neighbours offered my husband chicken biryani but we were not sure if the chicken was halaal or not since we've seen them before buying non halaal chicken but they argue that its halaal.

Q: I have heard that Hazrat Aasiyah (radhiyallahu anha) will be among the wives of Rasulullah (sallallahu alaihi wasallam) in Jannah, but I do not know whether this is true or not. Can I make dua to Allah Ta'ala to make me the husband of Hazrat Aasiyah (radhiyallahu anha) in Jannah?

Q: When I was younger, I was involved in petty crime (theft). Now that I am older, I realise my wrongdoing, and want to know how can I repay this debt.

2. I often took money from my late grandparents, without their knowledge. Now that they have passed away, how do I repay this debt?

3. I often took money from friends, without their knowledge. They are still alive, how do I repay this debt? Do I need to inform them of my transgression?

4. If I took R100, 20 years ago, what amount is due today? Is it the same amount or is there a calculation that I need to perform to allow for inflation?
