Inheriting from one's non-Muslim father before embracing Islam

Q: There is a lady who inherited money from her non-Muslim father many years ago. The inheritance was distributed according to government law in Portugal.

The lady has moved to South Africa after accepting Islam. The inheritance was given to her while she was a Muslim.

She currently stays with her husband here but they are struggling financially. What should she do with the money? Can she keep it or should she give it away? If it's the latter option, to whom should she give it to?

PRP (platelet rich plasma) treatment

Q: There is a treatment known as PRP (platelet rich plasma). In this treatment, blood is drawn from the patient and then inserted into a machine where it is spun for approximately 30 min until all the components of the blood separate.

It is then the plasma portion of the blood, which is rich in platelets and other proteins that promote healing and growth, that is re-injected into the affected site of the body e.g. an injured muscle, etc.

Generally, PRP is used to promote hair growth, assist with healing tendons and ligaments that are injured, assist with osteoarthritis, assist with healing brain damage, etc.

However, PRP is also used for cosmetic purposes. In this case, the PRP blood-mixture is applied to a person's face to stimulate the skin and make it look beautiful. This is referred to as a 'Vampire Facial'.

Is PRP permissible in Islam? If yes, then for which purposes is it permissible?

Road Accident Fund

Q: The road accident fund agrees to pay a person involved in a motor vehicle accident R100 000 for general damages. This agreement is taken to the high court so it can be made into a court order. The court order is made on 1 january 2017 that the road accident fund will pay the person R100 000. The court order further states: "In the event of the aforesaid amount not being paid timeously, the defendant shall be liable for interest on the amount at the rate of 10.25% per annum, calculated from the 15th calendar day after the date of this order to date of payment." The road accident fund pays the amount after 6 months of the court order and therefore interest is also received on top of the R100 000.

The question is: Is this extra amount received interest according to the shariah?
