"And fear a day when you will be returned to Allah; then every soul will be compensated for what it earned, and they will not be wronged." It means: they will not be diminished; that is to say: the believers will be paid their full good deeds on the Day of Resurrection.
﴿وَاتَّقُوا يَوْمًا تُرْجَعُونَ فِيهِ إِلَى اللَّهِ ثُمَّ تُوَفَّى كُلُّ نَفْسٍ مَا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ﴾ يَعْنِي: لَا ينقصُونَ؛ يَعْنِي: الْمُؤمنِينَ يُوفونَ حسناتهم يَوْم الْقِيَامَة. [آيَة]
