Waqifa, their sub-sects and other sects similar to them in belief

This post is based on this article[1]. I’ve covered Waqifa in a few other posts, but this entry will be more comprehensive and will cover the background of the Waqifa sects.

• The Waqifa sect stopped (waqafa) their line of Imams with the seventh Imam Musa al-Kadhim. They did not accept any other Imam after him.
• Another group called the Qafi'ya declared that Ali al-Rida was their new Imam after Musa al-Kadhim. The Shia Imamiyya has also accepted Ali al-Ridha as their eight Imam.
• A sect called the Mufawidda claimed that al-Husayn b. 'Ali b. Abi  Talib had NOT been killed in Karbala. They maintained that he was raised to the heavens just like Jesus who had been raised before.
• After the death of Muhammad b. al-Hanafiyya in 81 H or 700 AD, several groups, who were generally called the Kaysaniyya, declared that he had not died and he was the Qa'im.
• A sub-sect of Kaysaniyya believed that Muhammad al-Hanafiyyah was on the hill of Radwa between Mecca and Medina. He was nourished by God with food and drink. A lion on his right and a tiger on his left always protected him and this would continue until his reappearance.
• An extremist sect called the Bayaniyya believe his son, Aba Hasim ibn Muhammad al-Hanafiya, was also the Qaim. They stopped their line of Imams with him and started to wait for his reappearance.

But that’s not all. Even the father and grandfather of Imam Musa al-Kadhim were target of similar claims after their deaths.

• A small sect called the Baqiriyya believed in Imam Muhammad al-Baqir's concealment. The group maintained that he was the Mahdi-Qa'im and this fact had been told by the Prophet to Jabir b. 'Abd Allah, a Medinite disciple of the Prophet who is said to have met with al-Baqir. The Prophet told Jabir that he would meet the Qa'im and, when it would happen, he should give the Prophet's greeting to him.
• Another  group  called  the  Nawusiyya denied  al-Sadiq's  death  proclaiming  him  as  the  Qa'im.
• Similarly,  a  body  of  proto-Ismalis rejected the  death  of  Isma'il  b.  Ja'far  during  his  father's  lifetime  and  alleged  that  his  death  was  merely a plot of al-Sadiq's to save Ismail from the 'Abbasid persecution. Al-Shahrastani designates  this  group "al-Ismaliyya al- Waqifa".

All  these  groups  stopped (waqafa) their line of Imams with a particular Imam. The  name  Waqifa is  generally  used  in literature for those Shia's who believed Imam Musa al-Kadhim to be the  Qa'im.
