Although the term 'Imami' is synonymous with 'Twelver' when speaking about the period from c. 941 onward, it is also used by scholars to refer to that branch of early Shi'ism which would eventually develop into Twelver Shi'ism, before the number of Imams was fixed at twelve. The notion of twelve Imams is not yet found in the works of al-Barqi (died in 887 or 893), but a few hadiths mentioning that there would be twelve Imams were recorded by al-Saffar al-Qummi (died 903). The earliest text to unambiguously list the twelve Imams as we now know them is Ali ibn Ibrahim al-Qummi's (died 919) Tafsīr al-Qummī. Nevertheless, definitively fixing the number of Imams at twelve only became common from the time of al-Kulayni (died 941), and the doctrine that ultimately distinguished Twelver Shi'ism from earlier forms of Imami Shi'ism is the belief in the Major Occultation of the twelfth Imam Muhammad al-Mahdi, which occurred in 941 (the twelfth Imam was thought to have disappeared as a young boy in 874, initiating what is known as the Minor Occultation).

The concept of reincarnation into human (naskh), animal (maskh), or plant and mineral (raskh) bodies is also a common theme in other ghulāt texts. The Kitāb al-Haft wa-l-aẓilla goes a little bit further than the Kitāb al-Ṣirāṭ, also describing other forms of hierarchy within one class: among humans, female bodies rank below male ones, and among animals inedible species rank below edible ones; see Asatryan 2017, pp. 152–153. Some other forms, like waskh and faskh, are described in the context of Nusayri works by Friedman 2010, p. 106. Asatryan, Mushegh (2017).

The ghulāt were widespread in the 8th/9th century, but are now nearly extinct. The Nusayris or Alawites are the only ghulāt sect still in existence today (see Halm 2001–2012). Halm, Heinz (2001–2012). "Ḡolāt". In Yarshater, Ehsan (ed.). Encyclopædia Iranica.
Modaressi 2003, p. 333 also describes al-Mufaddal as a "leader of the Mufawwiḍa school of Shı̄‘ite Extremism". The heresiographers described the Mufawwiḍa as a ghulāt sect who believed that the Imams were delegated (Arabic: tafwīḍ) by God to perform divine tasks such as creating and sustaining the universe. However, Asatryan 2000–2012b notes that the hadith reports in which al-Mufaddal is credited with Mufawwiḍa views always end with a refutation of those views by the Imam. According to Asatryan 2017, pp. 98–111, tafwīḍ-like ideas often go hand in hand with the divinization of prophets and Imams as practiced by the ghulāt, and the concept of a separate group called the Mufawwiḍa is likely a mere construct of the heresiographers.

The earliest text to unambiguously list the twelve Imams as we now know them is Ali ibn Ibrahim al-Qummi's (died 919) Tafsīr al-Qummī. Nevertheless, definitively fixing the number of Imams at twelve only became common from the time of al-Kulayni (died 941), and the doctrine that ultimately distinguished Twelver Shi'ism from earlier forms of Imami Shi'ism is the belief in the Major Occultation of the twelfth Imam Muhammad al-Mahdi, which occurred in 941 (the twelfth Imam was thought to have disappeared as a young boy in 874, initiating what is known as the Minor Occultation).

Although the term 'Imami' is synonymous with 'Twelver' when speaking about the period from c. 941 onward, it is also used by scholars to refer to that branch of early Shi'ism which would eventually develop into Twelver Shi'ism, before the number of Imams was fixed at twelve. The notion of twelve Imams is not yet found in the works of al-Barqi (died in 887 or 893), but a few hadiths mentioning that there would be twelve Imams were recorded by al-Saffar al-Qummi (died 903).
