مَنْ عَمِلَ صَٰلِحًۭا مِّن ذَكَرٍ أَوْ أُنثَىٰ وَهُوَ مُؤْمِنٌۭ فَلَنُحْيِيَنَّهُۥ حَيَوٰةًۭ طَيِّبَةًۭ ۖ وَلَنَجْزِيَنَّهُمْ أَجْرَهُم بِأَحْسَنِ مَا كَانُوا۟ يَعْمَلُونَ
Whosoever doeth right, whether male or female, and is a believer, him verily we shall quicken with good life, and We shall pay them a recompense in proportion to the best of what they used to do.
