Last week, I went on a journey for 2 days. All I took with me was a sleeping bag and some clothes. Before that, I had to go visit some cities for a duration of 6 days. For that journey, I took with me many more items than I took for the 2 days journey. Few years back when I was visiting a different country for a longer period, I had to take large luggages with me. The point is that we prepare more for long journeys than short ones.
As a living being in this world, we are also planning for a journey that is coming after death. That journey is for a really long period of time. It starts from the grave and ends in Jannah. The only provision for that journey is our faith and good deeds. Are you ready for that journey?
