In Islam, stoning (Arabic: رجم, romanized: Rajm) is the Hudud punishment wherein an organized group throws stones at a convicted individual until that person dies. Under some versions of Islamic law (Sharia), it is the prescribed punishment in cases of adultery committed by a married person which requires either a confession from either the adulterer or adulteress, or producing four witnesses of sexual penetration.
The punishment of stoning as a capital punishment for adultery is unique in Islamic law in that it conflicts with the Qur'anic prescription for premarital and extramarital sex (zina) found in Surah An-Nur, 2: "The woman and the man guilty of adultery or fornication - flog each of them with a hundred stripes". For this reason some minority Muslim sects such as the former Kharijites, and Islamic modernists such as the Quranists disagree with the legality of stoning.
