Finding Internal Peace
كُلُّ نَفْسٍۢ ذَآئِقَةُ ٱلْمَوْتِ ۗ وَإِنَّمَا تُوَفَّوْنَ أُجُورَكُمْ يَوْمَ ٱلْقِيَـٰمَةِ ۖ فَمَن زُحْزِحَ عَنِ ٱلنَّارِ وَأُدْخِلَ ٱلْجَنَّةَ فَقَدْ فَازَ ۗ وَمَا ٱلْحَيَوٰةُ ٱلدُّنْيَآ إِلَّا مَتَـٰعُ ٱلْغُرُورِ
Every soul has to taste death. It is on the Day of Judgement that you shall be paid your rewards in full. So, whoever has been kept away from the Fire and admitted to Paradise has really succeeded. The worldly life is nothing but an illusionary enjoyment. [3:185]
In this ayat, Allah is telling us that no matter what, everyone will eventually die. Once we reach the Day of Judgement, that is when we will be rewarded for all the good we did in this life.
If we focus on doing good in this life, we will avoid entering the Fire and we will succeed in being granted Paradise. So do good, and don't get attached to the deception of this life, this Dunya. Remember that no matter how much money you have, how big your house is, or how new your car is. When you die, none of these materialistic things will come with you to the grave.
This world is only an illusionary enjoyment. Re-frame your perspective about your daily life so that you can find internal peace.
