The warning concerns a heart Allah has opened and illuminated toward good. Not every feeling is accepted as a sound judgment. This inward indication is restricted to matters without clear religious guidance or scholarly agreement. Clear religious guidance or scholarly agreement cannot be changed merely by personal comfort or public approval. Scholarly agreement means agreement among religious scholars, not simply majority opinion.
Dislike of disclosure also concerns upright, pious people who distinguish good conduct from bad. Feeling no shame among companions sharing the wrongdoing does not make it good. Teaching example: someone dislikes sharing a private detail publicly; that dislike alone does not establish sin.
If you are unsure how these conditions apply to a matter, do not decide that it is sinful from your feelings or your companions’ approval alone. Explain the matter to a trustworthy, knowledgeable religious scholar and seek guidance.
