Sayyiduna Ubadah bin Samit (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Take the ruling from me. Allah Almighty has made the ruling clear for them. For a married person committing adultery with another married person, one hundred lashes will be given and then stoning will be carried out. Whereas for an unmarried man with an unmarried woman (in the case of adultery), one hundred lashes will be given and they will be exiled for one year."
