[78] This verse affirms the principle of personal responsibility in faith and conduct: every believer is accountable for his own guidance and sincerity. Once a person fulfills his duty of advising others, calling to the truth, and forbidding evil, the persistence of others in error will not harm him—so long as he remains firm upon right guidance. The Prophet ﷺ said: “When people see wrong and do not stop it, it is likely that Allāh will encompass them all with punishment.”
