Qur'ān 45:30 · Al-Jathiyah (الجاثية)

فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ فَيُدْخِلُهُمْ رَبُّهُمْ فِى رَحْمَتِهِۦ ۚ ذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْمُبِينُ

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.
