Will Allah expose His servant after sincere repentance for a sin he committed, when his sin was not exposed during the entire period of its commission?

Praise be to Allah for guiding the young man to repent of his sin. We hope that Allah will not expose him, for Allah is Sattir (the Concealer of sins), who loves concealment. Imam Ahmad, Abu Dawud, and An-Nasa'i narrated that the Prophet, peace and blessings be upon him, said: "Indeed, Allah, the Exalted and Glorious, is Hayiyy (Modest) and Sattir (Concealer of sins); He loves modesty and concealment." If He concealed him while he was persisting in sin, then the hope is even stronger that He will conceal him after his repentance.
