Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: I have not seen anything that resembles sin more than what Sayyiduna Abu Hurairah (may Allah be pleased with him) has narrated, that the Prophet Muhammad (peace and blessings be upon him) said: "Allah Almighty has written the share of adultery for the son of Adam, which he will inevitably reach. So the adultery of the eye is looking, the adultery of the tongue is speaking, and the soul desires and wishes, and the private part either confirms it or denies it."
