Faith (Iman) as Foundation for Reward

مَنْ عَمِلَ سَيِّئَةً فَلَا يُجْزَىٰٓ إِلَّا مِثْلَهَا ۖ وَمَنْ عَمِلَ صَـٰلِحًا مِّن ذَكَرٍ أَوْ أُنثَىٰ وَهُوَ مُؤْمِنٌ فَأُو۟لَـٰٓئِكَ يَدْخُلُونَ ٱلْجَنَّةَ يُرْزَقُونَ فِيهَا بِغَيْرِ حِسَابٍ

Whoever does an evil deed will not be recompensed except by the like thereof; but whoever does righteousness, whether male or female, while he is a believer - those will enter Paradise, being given provision therein without account.
