Jazahka Allah for creating this thread sister.
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]. Nothing ever upsets the people of Paradise, not even the slightest word: “No laghw (dirty, false, evil vain talk) will they hear therein, nor any sinful speech (like backbiting, etc.), but only the saying of Salaam! Salaam! (greetings with peace).” [al-Waaqi’ah 56:25-26 – interpretation of the meaning].
It is also the nature of this life that people have to put up with suffering and hardship for various reasons, as is indicated in the Qur’aan (interpretation of the meaning): “Verily, We have created man in toil.” [al-Balad 90:4]. So people feel regret for what has happened in the past, anxious about what may happen in the future, and worried about what is going on in the present.
The things that cross our minds and make us feel distressed are things in the past that have caused grief, things in the future that we are worried about, and things in the present which concern us.
People react differently to stress and worries, depending on how many things are concerning them, whether the worry is continuous or not, and on whether they have faith in their hearts or are rebellious and sinful. We may describe people’s hearts as being of two types: either the heart is the throne of Allaah, filled with light, life, happiness, joy and all the treasures of goodness; or it is the throne of Shaytaan, wherein is distress, darkness, death, grief, worry and anxiety.
People’s worries and concerns will also differ, according to the differences in their motivations, circumstances and individual responsibilities.
