Q: I just want some advice regarding my predicament and also to request your Duas that Allah takes me out of this situation. I have been working in the banking/financial services industry for the last 11 years and at first did not realise that it was wrong but, in the last 6 years or so have been trying very hard to get out but to no avail. I have applied for many hundreds of jobs and I always make Taubah. I used to contribute in Allah's course but now I am scared to. I want to go for Umrah and Hajj but am worried that I will be sinning by doing so. I try to spend on my family within my capacity but always end up feeling depressed as I know where the money is coming from. What can I do to improve my chances of getting a better source of income?
