glad tidings to the strangers
I’m quite disappointed that this book didn’t really analyse the Surah in great detail but I did learn many things from it. Whilst Al-Kahf does deal with materialism and godlessness, this analysis fails to really explains this.
For a better analysis I would suggest you listen to Nouman Ali Khan‘s analysis and interpretation of the Surah cos that guy knows how to explain things! And you will also want to listen to Sheikh Imran Hosein‘s analysis too as he links the warnings from the Surah to modern times and shows you how you can use the lessons from it.
