An English translation of a book by Sheikh Muhammed Salih Al-Munajjid.

It is the nature of this life that people will suffer from worries and stress, because this world is the place of disease, hardship and suffering. Hence among the things that distinguish Paradise from this world is the fact that there is no worry or stress there: "No sense of fatigue shall touch them, nor shall they (ever) be asked to leave." [al-Hijr 15:48 – interpretation of the meaning].
