In the Uk we have a welfare state that supports the sick, pensions for the elderly, education mostly free, universal credit for those unable to work, maternity pay, etc, all paid for by taxation. It is a very good attempt at establishing a just social and economic system, though I do question stock-markets and interest rates.
N2I muslims can do their ritual prayers and give charity which is not salat and zakat, so they are enjoying the benefits of the UK without contributing to establishing and running it. Left to the mulla-gods they would have everyone praying and the UK system would collapse in a quick time.
Allah knows best, which means read the Qur'an and He explains why people fail over and over again and not that you promote a falsehood and get out of being responsible for it!
The idiots are those who have the Qur'an in their hands and look to Bukhari for the answers!
