My two cents

When you are sleeping, it is called die temporarily.( That's why don't sleep too much. There are so many things we can do to please God early in the morning between 3 a.m. and subuh time, like performing tahajjud prayer, zikri, reading Al Quran).

 When you are dead, it is called sleeping permanently. But you can sleep or rest in your grave only if the angels do not busy punishing you. So , how to avoid them is by being good . Always be good. is it so difficult to enter paradise? All depend on our intention. If we do so many good things but just because we want people to acknowledge us or to praise us, i don't think God approves of our action. Sometimes, we do a little thing, for example giving food to a very hungry little girl but we do it sincerely. We pity that girl and we only spent rm4 for her food but may be that's the reason for us to enter paradise. God is Ar Rahman and Ar Rohiim, that's why we must always be good to every living thing. ok good bye and take care.
