It is narrated from Abu Abdullah Al-Mu'min through Ishaq ibn Ammar who said: I asked Abu Abdullah عليه السلام: "Is adultery worse or drinking wine? And why is the punishment for drinking wine eighty lashes, while for adultery it is one hundred?" Imam عليه السلام replied: "O' Ishaq, the punishment is the same, but it was increased in the case of adultery because it involves wasting the seed and placing it in a place other than where Allah سبحانه وتعالى, the Almighty and Majestic, has commanded."
