No matter how hard you try, you can’t really be a “Modern Muslim” – which is an oxymoron. You’re not modern if you are looking to the past by seeking a 7th century moral lifestyle (Barbarians!?). This is because Islam didn’t bend or twist its rules or scriptures to change with the whims and desires of various societies, but this consistency of values is a strength, not a weakness.
The fact that we refer back to God and His Beloved Messenger (ﷺ) in helping us understand the difference between right and wrong helps us to remain consistent in our understanding, whilst the rest of society are like dry leaves blowing in the wind sometimes going this way and sometimes that way without steering any direction of their own; from Feudalism to Communism to Capitalism to not-yet-developed-ism.
