Quranism in the context of "Islamic denominations"

Islamic schools and branches have different understandings of Islam. There are many different sects or denominations, schools of Islamic jurisprudence, and schools of Islamic theology, or ʿaqīdah (creed). Within Sunnī Islam, there may be differences, such as different orders (tariqa) within Sufism, different schools of theology (Atharī, Ashʿarī, Māturīdī) and jurisprudence (Ḥanafī, Mālikī, Shāfiʿī, Ḥanbalī). Groups in Islam may be numerous (Sunnīs make up 87-90% of all Muslims), or relatively small in size (Ibadis, Ismāʿīlīs, Zaydīs).

Differences between the groups may not be well known to Muslims outside of scholarly circles, or may have induced enough passion to have resulted in political and religious violence (Barelvism, Deobandism, Salafism, Wahhabism). There are informal movements driven by ideas (such as Islamic modernism and Islamism), as well as organized groups with governing bodies (such as Nation of Islam). Some of the Islamic sects and groups regard certain others as deviant or not being truly Muslim (for example, Sunnīs frequently discriminate against Ahmadiyya, Alawites, Quranists, and sometimes Shīʿas). Some Islamic sects and groups date back to the early history of Islam between the 7th and 9th centuries CE (Kharijites, Mu'tazila, Sunnīs, Shīʿas), whereas others have arisen much more recently (Islamic neo-traditionalism, liberalism and progressivism, Islamic modernism, Salafism and Wahhabism), or even in the 20th century (Nation of Islam). Still others were influential historically, but are no longer in existence (non-Ibadi Kharijites and Murji'ah).

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.
