Yes — several Islamic (and Islam-adjacent) sects have organized prophets into trinities, heptads (7s), or other cyclical subgroups, usually as manifestations of divine light or emanations. These systems are esoteric, Gnostic-influenced, and rejected by orthodox Sunni/Shia scholars as shirk (polytheism).

Below are the major sects that do this, with exact groupings and sources.

---

1. Alawites (Nusayris) – 7 Trinities (Heptads)Core System: 7 historical cycles, each with a Trinity:
Maʿnā (Meaning/God) – Ism (Name/Prophet) – Bāb (Door/Disciple)

Cycle	Maʿnā (God)	Ism (Veil)	Bāb (Gate)
1	Abel	Seth	Idris
2	Noah	Adam	Seth
3	Abraham	Ishmael	Gabriel
4	Joshua	Moses	Aaron
5	Asaf	Solomon	David
6	Uzayr (Ezra)	Jesus	Simon Peter
7	ʿAlī	Muhammad	Salmān al-Fārisī

2. Druze (Muwahhidun) – 5 Cosmic Luminaries + 1 TrinityA. Pentad of Limits (Ḥudūd) – Core divine hierarchy

Rank	Figure	Role
1	al-Ḥākim bi-Amr Allāh	God incarnate (final Maʿnā)
2	Hamza ibn ʿAlī	Universal Intellect (ʿAql)
3	Ismāʿīl al-Tamīmī	Universal Soul (Nafs)
4	Muḥammad ibn Wahb	The Word (Kalima)
5	Salmān al-Tamīmī	The Preceder (Sābiq)

B. Historical Trinity (Echo of Alawites)

• ʿAlī → Muhammad → Salmān (acknowledged but superseded by al-Ḥākim)

3. Ahl-e Haqq (Yarsan / Kaka’i) – 7 Divine Avatars (Haft Tan)7 successive manifestations of God, each with angelic companions:

Avatar	Historical Figure	Angelic Form
1	Khawandgar (God)	Gabriel
2	ʿAlī ibn Abī Ṭālib	Mikāʾīl
3	Abu’l-Wafāʾ	Isrāfīl
4	Sultan Sahak (final)	ʿAzrāʾīl
5–7	Various saints	Lesser angels

Also: 1,001 incarnations of the 7 archangels in human form.Source: Saranzam (sacred hymns), oral tradition

4. Ismailis (Nizari & Bohra) – 7 Speaking Prophets (Nāṭiqs)Not trinities, but cyclical heptads:

Cycle	Nāṭiq (Speaking Prophet)	Sāmīt (Silent Imam/Foundation)
1	Adam	Shīth (Seth)
2	Nūḥ (Noah)	Sām (Shem)
3	Ibrāhīm	Ismāʿīl
4	Mūsā	Hārūn
5	ʿĪsā	Shamʿūn al-Ṣafā (Simon Peter)
6	Muḥammad	ʿAlī
7	al-Qāʾim (Mahdi)	Future Imam

Note: No reincarnation, but divine light passes from Nāṭiq → Imams.

5. Early Ghulat Sects (8th–10th c.) – Trinities & Tafsīr

Sect	Trinity	Notes
Khatṭābiyya	ʿAlī – Muḥammad – Abū al-Khaṭṭāb	Abū al-Khaṭṭāb as Bāb
Mufawwiḍa	God → ʿAlī → 12 Imams	Delegation of creation
ʿAlawiyya (pre-Nusayri)	ʿAlī – Muḥammad – Salmān	Direct precursor

---

6. Alevis (Anatolia) – Loose Trinity + 7/12 Ulū’l-ʿAzmA. Trinity of God

• Allah – Muḥammad – ʿAlī (sometimes merged as one light)
• Ritual chant: “Allah, Muhammad, ʿAlī bir nurdur” ("are one light")

B. 7 Great Prophets (Yedi Ulu) – in Buyruk texts

1. Adam
2. Noah
3. Abraham
4. Moses
5. Jesus

Sect	Grouping	# of Units	Reincarnation?	Divine Human?	Source
Alawites	7 Trinities	21 figures	Yes	Yes (Maʿnā = God)	Kitāb al-Majmūʿ
Druze	1 Pentad + 1 Trinity	5 + 3	Yes	Yes (al-Ḥākim)	Rasāʾil al-Ḥikma

Why These Systems Exist

1. Gnostic Influence: Soul cycles, emanations, fall/redemption.
2. Neoplatonism: Hierarchy of being (One → Intellect → Soul).
3. Shia Extremism (Ghuluww): Elevating ʿAlī above prophets.
4. Syncretism: Absorbing Christian trinities, Zoroastrian heptads.
