Working as a research analyst in a stock brokerage firm

Q: I wanted to ask a question about the job of research analyst in a stock brokerage firm or mutual fund. My degree major is finance so I want to know if working as a research analyst for any stock market company is halaal? Basically, the job is to do research on companies, look at their financial statements and analyse their performance and then give a recommendation on whether to buy the stock or sell it. I understand that investing in Shari'ah compliant stocks are allowed but I won't be investing. I'll just be researching and giving opinions. Also, I won't be researching on banks and insurance companies whose business is unlawful. So is this job halaal?

Performing Salaah in jamaat on the plane

Q: If one is travelling in a plane and wants to read salah with another brother in jamaat, in the limited space at the back of the plane would it be permissible due to space being limited:

  1. The imam stands directly in front of a single muqtadi?
  2. The imam stands almost next to muqtadi, just a few centimetres in front (due to space restrictions the ideal of one foot behind the imam cannot work)?
  3. The imam stands on the right of the muqtadi, muqtadi behind imam one foot length?
