إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ
“Indeed, those who believe and do righteous deeds.”
The conjunction wa joins faith and righteous action. One argument takes the coordinated wording to distinguish the concepts: belief and deeds are mentioned separately, so deeds are not identical with the core definition of belief.
An objection notes that language can coordinate a part with its whole. Thus the argument must be assessed alongside broader usage and other texts. A conjunction by itself need not settle every dimension of the debate.
