Is the implementation of hudud (the fixed Qur'anic punishments) an expiation for those who commit them?

Question:
May Allah bless you. This is a Sudanese questioner who says: If a person commits a crime and the Shari'ah ruling for that crime is carried out against him, does he still face punishment for this same crime in the Hereafter?

Answer:
This is a matter of scholarly disagreement among the people of knowledge. Some say that the hudud are expiations and purifiers, and that Allah the Exalted does not combine two punishments—a punishment in this world and a punishment in the Hereafter—for a single sin. Other scholars say that the hudud are merely deterrents; yes, they are merely deterrents, and they do not prevent punishment in the Hereafter. As for the proponents of the first opinion, they hold that the hudud are expiations, while those who hold that the hudud are deterrents hold that view. In any case, if the servant repents to Allah while the hudud is carried out against him, then Allah will accept his repentance. If he repents from the sin, seeks forgiveness, and the hudud is carried out against him, then Allah will accept his repentance and exempt him from the punishment of the Hereafter. However, if he does not repent, this is the matter of disagreement we mentioned among the people of knowledge. Yes.
