Great advice by Duke
You need give up on this mentality of getting rich quick, you have <1% chance in this and look at it from a long term perspective. The best returns and least risky is buying land in Somalia, only do this if you have family there.
£50.000 is not enough for the inner cities, so you will have to buy in the outskirts, watch out for large scale economic movement/plans e.g. Berbera UAE deal those that bought land very early before anything was reported will make a killing.
I did a similar thing, before anyone knew about the Turkish base plan's or before it was reported, I bought plots of land close to it, and now some more close to the proposed second airport in Xamar, the only way you know this information is if your on top of it, don't need much links for this, almost like insider trading.
I would split it 40% land acquisition, 5% Sadaqah (it only increases your wealth), 55% kept in an Islamic bank for a whole year for low risk guaranteed returns, it will be your emergency fund while you continue your Job. Building wealth is not get rich quick scheme as most people think
