Ta-Ha - 20:112

وَمَن يَعْمَلْ مِنَ الصَّالِحَاتِ وَهُوَ مُؤْمِنٌ فَلَا يَخَافُ ظُلْمًا وَلَا هَضْمًا
[20:112]
And whoever does good works and he is a believer, he shall have no fear of injustice nor of the withholding of his due.
But he who works deeds of righteousness, and has faith, will have no fear of harm nor of any curtailment (of what is his due).
And he who hath done some good works, being a believer, he feareth not injustice nor begrudging (of his wage).
