Justice of Allah on the Day of Judgment

إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَٱلَّذِينَ هَادُوا۟ وَٱلنَّصَـٰرَىٰ وَٱلصَّـٰبِـِٔينَ مَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَعَمِلَ صَـٰلِحًا فَلَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muḥammad (ﷺ)] - those [among them] who believed in Allāh and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.

أُو۟لَـٰٓئِكَ ٱلَّذِينَ حَبِطَتْ أَعْمَـٰلُهُمْ فِى ٱلدُّنْيَا وَٱلْـَٔاخِرَةِ وَمَا لَهُم مِّن نَّـٰصِرِينَ

They are the ones whose deeds have become worthless in this world and the Hereafter, and for them there will be no helpers.
