Transience of worldly life (dunya)

مَا عِندَكُمْ يَنفَدُ ۖ وَمَا عِندَ ٱللَّهِ بَاقٍ ۗ وَلَنَجْزِيَنَّ ٱلَّذِينَ صَبَرُوٓا۟ أَجْرَهُم بِأَحْسَنِ مَا كَانُوا۟ يَعْمَلُونَ

Whatever you have will end, but what Allāh has is lasting. And We will surely give those who were patient their reward according to the best of what they used to do.
