Answer: As it is been said earlier, some historians have completely denied the existence of Abdullah Ibn Saba, considering him a purely fictional character with no real historical basis. As a result, they reject his alleged role in the sedition and assassination of Caliph Uthman. Below are the views of some scholars on this matter:
1. Muhammad ibn Abdul Hayy Sha‘ban
Despite extensively covering the sedition surrounding Uthman’s assassination and the related conflicts, this historian does not mention Ibn Saba or the Sabaiyyah (his alleged followers) at all in his book. (Reference: 475)
2. Hashim Ja‘it
Following the same approach, Hashim Ja‘it has conducted an even more comprehensive study on the sedition of Uthman’s assassination. He concludes:
"The narration that portrays Abdullah Ibn Saba as the central figure in the sedition is completely unacceptable." (Reference: 476)
3. Ahmad Lawasani
In his book, Ahmad Lawasani argues that the entire story of Abdullah Ibn Saba was fabricated by influential Jewish figures and later introduced into Islamic history. He suggests that these individuals only pretended to convert to Islam to achieve their hidden objectives. (Reference: 477)
These historians, among others, reject the traditional narrative of Abdullah Ibn Saba’s role and believe his story was artificially inserted into Islamic history for political or sectarian purposes.
4. Egyptian Author: Ahmad Abbas Saleh
In his book "Al-Yamin wal Yasar fi al-Islam" (The Right and Left in Islam), Ahmad Abbas Saleh states:
"Here, the name of Abdullah Ibn Saba frequently appears—described as a Jewish man who converted to Islam. Historical books depict him as a devil behind the assassination of Uthman and, in fact, behind all major conflicts and seditions... Writers have taken contradictory stances regarding him; some completely deny his existence, while others consider him the root of every strange and deviant sect that entered Islam. Without a doubt, Abdullah Ibn Saba is a mythical figure." (Reference: 484)
This statement reinforces the idea that Ibn Saba's story is largely fabricated or exaggerated, serving as a scapegoat for historical events.
5. Dr. Abdul Aziz Halabi
In his book titled "Abdullah Ibn Saba", Dr. Abdul Aziz Halabi states:
"In summary, our conclusion regarding Abdullah Ibn Saba is that he is an imaginary figure with no real existence. And even if he did exist, he certainly would not have had the audacity to play the role that Sayf ibn Umar attributed to him—neither politically nor ideologically." (Reference: 481)
This statement also supports the view that Ibn Saba is either a fictional character or, at most, a historically insignificant figure whose role in Islamic history has been greatly exaggerated or fabricated.
