What is the ruling on one who called for committing an abomination then retracted before doing so, and will the legal punishment (hadd) in this world suffice for the punishment in the afterlife, and what is the difference between his situation and that of the seven whom Allah will shade with His shade on a Day when there is no shade but His?

Establishing the Sharia-ordained punishment upon one who commits indecency atones for their sin. Avoiding indecency is an act for which a servant is rewarded if they are sincere. There is a difference between one who abstains from indecency after being invited to it and one who goes to dens of evil with bad companions. Going to dens of evil with bad companions is a sin that requires repentance and abandoning these companions.
