Allāh ﷻ says in the Holy Qur’ān that whoever does even an atom’s weight of good or evil will see it. Every deed is recorded and nothing is lost. Sins against Allāh ﷻ may be forgiven through repentance and worship, but wrongdoing against people is only forgiven when they pardon it. Be careful not to violate anyone’s rights, for the consequence may remain until the Day of Judgement.
