Here is a way to assess where you stand after reviewing this Hadith. Sorry I don’t have the detailed tafseer on it, perhaps you can search and study it yourself. But do take the test of what is dunya to you?
قال رسول الله (ص) : ( الدنيا سجن المؤمن وجنة الكافر)
The Prophet PBUH said:: The Dunia is the prison of the believer, and the paradise of the kaafir.
