Hadith on Sin: One who is pleased with sin is like a witness to it

Al-‘Urs ibn ‘Amirah reported: The Prophet, peace and blessings be upon him, said, “When sin is committed on the earth, whoever witnessed it and hated it and rejected it will be like one who was absent from it. Whoever was absent from it and was pleased with it will be like one who witnessed it.”
