The masjids lack speaking about Hijrah and plans to make it. Maybe because many have immigrated and settled in the west and the urge and motivation lacks with the primary concern to establish communities where they are. This however in my opinion goes against what is meant to be Islamicaly and principles of leaving non-Muslim lands to be with ones own peoples (of believers, Emaan and rule) which has hundreds of benefits for the Muslim and fulfilling ones Islamic objectives.
What you can do (from the UK).
- Buy a property (50k) which can give you a 10% yield. (this would amount to £5-6,000 passive income). North east of UK, via auction sites, multi room letting.
- invest in gold bullion (20 k) which can give you a 10-15% yield tax free (from the royalmint.com) (£2500)
- If possible start something online which can return you £100 to £200 monthly income.
This establishes some sort of passive income
This is a base and you must continually build on this if possible.
For Qatar I would recommend buying a coffee shop (40k) getting the business visa and moving the family. Whatever country I would recommend seeking the business (company) visa (can be easiest way to relocate) after this using your skills.
Lastly using your skills to earn an income.
If you have no skills look at driving opportunities or teaching English in the country or some sort of manual work with skills (Air conditioning engineer, Heavy truck driver).
Plan this before relocating. Western skills are respected in the Muslim world.
