"And he—peace be upon him—emphasized this meaning with his saying: 'Indeed, the one who performs them in secret is like the one who abandons them in public, and the one who abandons them in public is like the one who performs them in secret.'"

"The meaning of that is that the one who performs them in secret has contradicted the narrations that forbid their performance, just as the one who abandons them among the Opposites [the deniers/enemies] has contradicted the narrations commanding their performance. For the one who performs them in secret for the purpose of worship, Allah does not accept from him due to his belief in them; just as the one who abandons them among the Opposites, Allah does not accept from him because of his failure to veil their Inward by performing their Outward in accordance with the commanded Dissimulation (taqiyya)."

"What indicates that the Outward is opposite to the Inward and vice versa is what came in the previously mentioned verse:

{Its interior contains mercy, and its exterior is toward the punishment.} (Al-Hadid: 13).

For punishment is the opposite of mercy, just as mercy is the opposite of punishment."
