A sect from the "Raafidah" believing in the imamate of Musa ibn Ja`far al-Kaazhim.
"Al-Moosawiyyah" is a sect from the "Raafidah" named after Musa al-Kaazhim. They said that Ja`far as-Saadiq stated that the imamate (position of Imam or Muslim leader as per the Shiite belief) was to be transferred to his son Musa al-Kaazhim. They have the same beliefs as the Twelvers , for example: 1. They abuse the Companions of the Prophet and accuse them of disbelief. 2. They believe that the Qur'an was tampered with. 3. They worship graves and idols. 4. They believe in "taqiyyah" (precautionary dissimulation), "raj`ah" (the Return), and in "mut`ah" (fixed term) marriage. Al-Moosawiyyah have split into sects. One sect said that Musa al-Kaazhim died and that the imamate was transferred to his son `Ali ar-Rida. These are the Twelver "Raafidah" who are also called "Al-Qat’iyyah". Another sect, which was called “Al-Mamtoorah", said that they were not sure if Musa al-Kaazhim died or not. A third sect, called “Al-Waqfiyyah", calimed that he was just absent and would come back, hence, they did not assign the imamate to anyone after him.
“Al-Moosawiyyah”: a sect named after a man called Musa whom they followed.
A Shia sect, named after Mūsa al-Kāẓim because they claimed that ‘the Imamat [i.e. The status of Imam] was bequeathed by JaꜤfar al-Ṣādiq to his son Mūsa al-Kāẓim by his clear statement. The Abbasid Caliph, Hārūn al-Rashīd, then took Mūsā to Baghdad and imprisoned him for declaring himself as Imam, but he never came out of prison, and we doubt that he died’. Al-Mūsawiyyah later split into two groups: those who said that Mūsa al-Kāẓim died, and they are called QaṭꜤiyyah, i.e. Finalists; and those who said: ‘we do not know whether he died or not’. They were called al-Mamṭūrah, i.e. drenched by rain, because Zurārah ibn AꜤyan said to them: ‘To me, you are less than dogs drenched by rain’, referring to the fact that people chase such dogs away.
