Is Islam a static religion?

Re: Is Islam a static religion?

Greed and 'needs' have no boundaries!

You are giving an example of day to day scenario in the settings which are created over decades. Buying insurance is one good way to start for medical expenses. Thats not paying interest or getting one. Ever heard of 'insurance' in your 'modern' world?
Besides a good welfare society can take care of needy.

There are people who ARE living in this world and have never paid and refused to get interest and are happy even in any islamic or non-islamic country.

Its an individual decision at the end of the day no matter how you look at.

Besides, you mentioned about islamic institutions and their interest free loans. Many are real.

There are and have been a great number of people who would give interest free loan to someone reaaly in trouble.

Please take time to search and seek.
