Is guiding an adulteress to repentance and concealment, and not disclosing her crime to her suitor or husband, considered a form of deception? And are those who repent from adultery equal in reward and recompense to those who strived against their desires and avoided the forbidden?

The encouragement for sinners to repent and conceal their sins is what the Sharia has brought. Therefore, a wife concealing her own sin if she falls into error is not considered deception towards her husband, because informing the husband of the error does not change its reality; rather, it may lead to the destruction of the family and the scattering of the children. The same applies to the husband if he falls into error. The Prophet, peace and blessings be upon him, said: "Whoever is afflicted with any of these abominations, let him seek forgiveness from Allah, the Most High." So, it is better for whoever falls into error to repent to Allah and seek concealment under Allah's cover, and not expose himself, because declaring the error destroys virtue and spreads vice. Moreover, it sullies the honor of the wife, her husband, and her family, and exposes her children to doubt and accusation regarding their lineage. Repentance erases the sin, but openly declaring it does not remove its disgrace.
