The comparison رَجَعَ كَيَوْمِ وَلَدَتْهُ أُمُّهُ conveys the hope of returning spiritually cleansed. It should also inspire a resolve to avoid further wrongdoing.
Example 1: Existing debts still require payment or a legitimate settlement; performing Hajj is not an automatic cancellation of financial obligations.
Example 2: If a person has harmed someone, seeking forgiveness where appropriate, repairing loss, and changing conduct are part of genuine reform.
The promise of worship is therefore understood alongside continued duties toward other people.
