Employment contract

Q: A father has a business and employs his son as a manager of the business. The father stipulates the salary of the son as follows: 

On a monthly basis the son will receive R2000 (for example) as salary, which will escalate 10% yearly, and together with that, the son will share 50% of the profits yearly with the father, after deducting business expenses. Is this permissible?

Dream

Q: I had a disturbing dream last night and wish for Mufti to please interpret this for me. I am in Hijaab. I saw myself at a gathering. Someone asked me to move to another spot to sit. As I walked across I was tieing my scarf again, and as I turned it around, the bottom end of the scarf hit the light bulb and caught alight. It was a small little flame and I tried to hit it off with my hand, but it did not go off. I then recited Allahu Akbar loudly a few times, and the flame died off immediately. Please can you tell me what this possibly means?
