Rejection of worldly pursuits as primary goal

أُو۟لَـٰٓئِكَ ٱلَّذِينَ لَيْسَ لَهُمْ فِى ٱلْـَٔاخِرَةِ إِلَّا ٱلنَّارُ ۖ وَحَبِطَ مَا صَنَعُوا۟ فِيهَا وَبَـٰطِلٌ مَّا كَانُوا۟ يَعْمَلُونَ

Those are the ones for whom there is not in the Hereafter but the Fire. And lost is what they did therein, and worthless is what they used to do.
