I want to know that if I were to die right now what would my death be like? Would it be painful, would it be pleasurable, would it be sweet?
Here is an answer to your question?
Your death will be exactly as your prayer is to you right now. Why? because when you pray Salah what do you do? You go and meet Allah. When you die what happens? You go and meet Allah. If you dislike meeting Allah while you are in this world, why would you want to meet Allah when you leave the body?
If Salah is sweet to you right now your death would be sweet if you die right now. If you eagerly wait for Salah, then when death comes to you, you will eagerly wait to be released from this cage and soar to new heights. If your Salah is a burden on you right now, death will be a burden on you if you die right now.
If Salah is painful, death will be painful. Look at your Salah, improve your Salah, and you will improve your connection to Allah because both of these are nothing but a meeting with Allah.
Ya Allah forgive our sins and help us to improve our Salah (Ameen)
