Permissible and Impermissible employment

Q: I am a female lawyer. Is it permissible for me to work in Pakistan courts?

Q: My husband knows some people who makes cards for work. They asked him to get people who want cards. If people go by themselves, they have to pay 80£ to do the test. If they fail the test they not going to get the card. But if you pay more, they can get the card for you without doing the test and you have to pay around 200£.

So my husband gets people and tells them it's 300£ for the cards. He takes them to get the cards and explains everything to them. He takes the money and pays 200£ to the people making the cards and takes 100£ for himself. Is this halal or is it a kind of riba? 

Q: I am a computer science PhD and I want to specialize in Computer Vision. Please allow me to explain what this does with examples:

1. Self-driving cars use computer vision techniques to "perceive" the surroundings and make decisions (avoid passengers, avoid trees, recognize road sighs, etc.)

2. Security camera uses computer vision for smart, precise facial recognition (not the blurry survey cams)

While these seem to be permissible, it is important to know that this technique is built upon (especially for self-driving cars):

- use camera/sensor to gather data (mostly images/photos/other data) --> cleanly visualize the image by rebuilding the images in 3D--> construct math model for the images --> provide instruction for next move.

As you can see, in order for it to work researchers and engineers must take photos with cameras on car. They also need to build 3D models in computer of human, cars, animals, trees, etc. It is well-known that takings photos, making images, and 3D images of human beings is haraam (not permissible), even though the technology (computer vision) is extremely useful, even for Muslims and Muslim countries (the applications are too many to be named).

Can I study this field and work in this field?

Q: Can I work in this job?

“Radiology Support Workers are valued members of the Radiology department. We are now seeking to expand this team and are looking to recruit a caring, hardworking and enthusiastic individual. You should be reliable, self-motivated and flexible with excellent communication and inter-personal skills.

You will work closely with Radiologists, Radiographers, Administrative staff and other Radiographic Assistants. Duties will be in all areas of the department and include; assisting with patients and examinations, room preparation, data input onto the department computer system ordering and maintenance of department stock, general housekeeping, undertaking clerical duties and liaising with wards and clinicians.

We are a forward-looking department committed to training and role development.”

Amongst the requirments of working in a hospital is obviously respecting all people and treating all like equals. I worry that if I apply for the job saying that I agree with this, I’d be lying, because realistically it isnt true. For example, men and women arent equal and another example - what if a patient/co worker is homosexual, I dont agree and respect their haraam practices.
