Is it permissible to supplicate for the erasure of something from people's memories, and is that considered an transgression in supplication?

There is no harm in a servant's supplication that their scandal be forgotten, for it is a prayer for the concealment of one's faults. It is not impossible for people to forget a person's scandal; how many a penitent's repentance was good, and they became known for good deeds, and people forgot their past. The servant should make God's pleasure their ultimate goal through sincere repentance, so that God may make a way out for them; for the penitent are among the pious, and God loves the repentant and the doers of good. And if God loves a servant, He casts their love into the hearts of His servants. Beware of the sadness that hinders you from reforming yourself and from increasing in good deeds.
