Surah Al-Jathiyah, ayah 30

فَأَمَّا ٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّٰلِحَٰتِ فَيُدۡخِلُهُمۡ رَبُّهُمۡ فِي رَحۡمَتِهِۦۚ ذَٰلِكَ هُوَ ٱلۡفَوۡزُ ٱلۡمُبِينُ ٣٠

Fa ammal-ladhīna āmanū wa'amilus-sālihāti fayudkhiluhum rabbuhum fī rahmatihī dhālika huwal-fawzul-mubīn

So as for those who believed and did righteous deeds, their Lord will admit them into His mercy. That is what is the clear attainment.
