الَّذِينَ آمَنُوا وَلَمْ يَلْبِسُوا إِيمَانَهُمْ بِظُلْمٍ
Those who believe and do not mix their belief with wrongdoing. (6:82)
The Companions feared that everyone commits some wrong. The Prophet ﷺ explained that the ẓulm intended here is shirk, as clarified by the statement “Associating partners is a tremendous wrong” (31:13).
