صحیح مسلم · Hadith 4417

Ubada b. as-Samit reported that whenever Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) received revelation, he felt its rigour and the complexion of his face changed. One day revelation descended upon him, he felt the same rigour. When it was over and he felt relief, he said: Take from me. Verily Allah has ordained a way for them (the women who commit fornication),: (When) a married man (commits adultery) with a married woman, and an unmarried male with an unmarried woman, then in case of married (persons) there is (a punishment) of one hundred lashes and then stoning (to death). And in case of unmarried persons, (the punishment) is one hundred lashes and exile for one year.
