'''Abdullah son of Sheba''' (ca. 600 CE), also known as '''Ibn [[Sawda]]''' (after his mother) was probably one of Al-Ansaar [[Sabaeans]] and a leader of the Sabi'een after Muhammad (PBUH) who were opposed to the reformation of Petrine Sabi'ism by the Caliphate into Imperial Islam. His stance was later used as the foundation for the later sect of the Shiites, although this is disputed.
