What are the proofs from the Qur’an and Sunnah that confirm "as you condemn, so shall you be condemned" to warn young men and women against tampering with the honor of others, and to explain that whoever does so may have someone سلط عليه [appointed over him] who will do the same to the women of his family?

The hadith "As you condemn, you will be condemned" is weak, and likewise, the hadith "Whoever commits adultery will have adultery committed against him, even within the walls of his own house" is fabricated. It is not necessarily the case that if a person commits a sin, their family will fall into the same sin, for "No bearer of burdens will bear the burden of another."
